Chapter 1. Introduction

What are Kickstart Installations?

Many system administrators would prefer to use an automated installation method to install Fedora or Red Hat Enterprise Linux on their machines. To answer this need, Red Hat created the kickstart installation method. Using kickstart, a system administrator can create a single file containing the answers to all the questions that would normally be asked during a typical installation.

Kickstart files can be kept on a server system and read by individual computers during the installation. This installation method can support the use of a single kickstart file to install Fedora or Red Hat Enterprise Linux on multiple machines, making it ideal for network and system administrators.

The Fedora installation guide at http://docs.fedoraproject.org/en-US/index.html has a detailed section on kickstart.

How Do You Perform a Kickstart Installation?

Kickstart installations can be performed using a local CD-ROM, a local hard drive, or via NFS, FTP, or HTTP.

To use kickstart, you must:

1. Create a kickstart file.
2. Create a boot diskette with the kickstart file or make the kickstart file available on the network.
3. Make the installation tree available.
4. Start the kickstart installation.

This chapter explains these steps in detail.

Creating the Kickstart File

The kickstart file is a simple text file, containing a list of items, each identified by a keyword. You can create it by using the Kickstart Configurator application or by writing it from scratch. The Fedora or Red Hat Enterprise Linux installation program also creates a sample kickstart file based on the options that you selected during installation. It is written to the file /root/anaconda-ks.cfg. You should be able to edit it with any text editor or word processor that can save files as ASCII text.

First, be aware of the following issues when you are creating your kickstart file:

• While not strictly required, there is a natural order for sections that should be followed. Items within the sections do not have to be in a specific order unless otherwise noted. The section order is:
  1. Command section -- Refer to Chapter 2 for a list of kickstart options. You must include the required options.
  2. The %packages section -- Refer to Chapter 3 for details.
  3. The %pre, %post, and %traceback sections -- These sections can be in any order and are not required. Refer to Chapter 4 and Chapter 5 for details.
• The %packages, %pre, %post and %traceback sections are all required to be closed with %end
• Items that are not required can be omitted.
• Omitting any required item will result in the installation program prompting the user for an answer to the related item, just as the user would be prompted during a typical installation. Once the answer is given, the installation will continue unattended unless it finds another missing item.
• Lines starting with a pound sign (#) are treated as comments and are ignored.
• If deprecated commands, options, or syntax are used during a kickstart installation, a warning message will be logged to the anaconda log. Since deprecated items are usually removed within a release or two, it makes sense to check the installation log to make sure you haven't used any of them. When using ksvalidator, deprecated items will cause an error.
• For kickstart upgrades, the following items are required:
  1. Language
  2. Installation method
  3. Device specification (if device is needed to perform installation)
  4. Keyboard setup
  5. The upgrade keyword
  6. Boot loader configuration

If any other items are specified for an upgrade, those items will be ignored - this includes package selection.

Special Notes for Referring to Disks

Traditionally, disks have been referred to throughout Kickstart by a device node name (such as sda). The Linux kernel has moved to a more dynamic method where device names are not guaranteed to be consistent across reboots, so this can complicate usage in Kickstart scripts. To accommodate stable device naming, you can use any item from /dev/disk in place of a device node name. For example, instead of:

part / --fstype=ext4 --onpart=sda1

You could use an entry similar to one of the following:

part / --fstype=ext4 --onpart=/dev/disk/by-path/pci-0000:00:05.0-scsi-0:0:0:0-part1
part / --fstype=ext4 --onpart=/dev/disk/by-id/ata-ST3160815AS_6RA0C882-part1

This provides a consistent way to refer to disks that is more meaningful than just sda. This is especially useful in large storage environments.

You can also use shell-like entries to refer to disks. This is primarily intended to make it easier to use the clearpart and ignoredisk commands in large storage environments. For example, instead of:

ignoredisk --drives=sdaa,sdab,sdac

You could use an entry similar to the following:

ignoredisk --drives=/dev/disk/by-path/pci-0000:00:05.0-scsi-*

Finally, anywhere you want to refer to an existing partition or filesystem (say, in the part --ondisk=) option, you may also refer to the device by its filesystem label or UUID. This is done as follows:

part /data --ondisk=LABEL=data
part /misc --ondisk=UUID=819ff6de-0bd6-4bf4-8b72-dbe41033a85b

Chapter 2. Kickstart Options

The following options can be placed in a kickstart file. If you prefer to use a graphical interface for creating your kickstart file, you can use the Kickstart Configurator application.

If the option is followed by an equals mark (=), a value must be specified after it. In the example commands, options in [square brackets] are optional arguments for the command.

pykickstart processes arguments to commands just like the shell does. If a list of arguments can be passed in, the arguments must be separated by commas and not include any extra spaces. If extra spaces are required in the list of arguments, the entire argument must be surrounded by double quotes. If quotes, spaces, or other special characters need to be added to the argument list, they must be escaped.

auth or authconfig

This required command sets up the authentication options for the system. This is just a wrapper around the authconfig program, so all options recognized by that program are valid for this command. See the manual page for authconfig for a complete list.

By default, passwords are normally encrypted and are not shadowed.

autopart

Automatically create partitions -- a root (/) partition, a swap partition, and an appropriate boot partition for the architecture. On large enough drives, this will also create a /home partition. One or more of the default partition sizes can be redefined with the part directive.

--type=<type>

Select automatic partitioning scheme. Must be one of the following: lvm, btrfs, plain. Plain means regular partitions with no btrfs or lvm.

--encrypted

Should all devices with support be encrypted by default? This is equivalent to checking the "Encrypt" checkbox on the initial partitioning screen.

--passphrase=

Only relevant if --encrypted is specified. Provide a default system-wide passphrase for all encrypted devices.

--escrowcert=<url>

Only relevant if --encrypted is specified. Load an X.509 certificate from <url>. Store the data encryption keys of all encrypted volumes created during installation, encrypted using the certificate, as files in /root.

--backuppassphrase

Only relevant if --escrowcert is specified. In addition to storing the data encryption keys, generate a random passphrase and add it to all encrypted volumes created during installation. Then store the passphrase, encrypted using the certificate specified by --escrowcert, as files in /root (one file for each encrypted volume).

--cipher

Only relevant if --encrypted is specified. Specifies which encryption algorithm should be used to encrypt the filesystem.

autostep

Kickstart installs normally skip unnecessary screens. This makes the installer step through every screen, displaying each briefly.

This is mostly used for debugging.

--autoscreenshot

Take a screenshot at every step during installation and copy the images over to /root/anaconda-screenshots after installation is complete. This is most useful for documentation.

bootloader

This required command specifies how the boot loader should be installed.

BIOS Boot partition
As of Fedora 16 there must be a biosboot partition for the bootloader to be installed successfully onto a disk that contains a GPT/GUID partition table, which includes disks initialized by anaconda. This partition may be created with the kickstart option part biosboot --fstype=biosboot --size=1. However, in the case that a disk has an existing biosboot partition, adding a "part biosboot" option is unnecessary.

--append=

Specifies kernel parameters. The default set of bootloader arguments is "rhgb quiet". You will get this set of arguments regardless of what parameters you pass to --append, or if you leave out --append entirely. For example:

bootloader --location=mbr --append="hdd=ide-scsi ide=nodma"

--boot-drive=

Specifies which drive the bootloader should be written to and thus, which drive the computer will boot from.

--leavebootorder

On EFI or ISeries/PSeries machines, this option prevents the installer from making changes to the existing list of bootable images.

--driveorder

Specify which drive is first in the BIOS boot order. For example:

bootloader --driveorder=sda,hda

--location=

Specifies where the boot record is written. Valid values are the following: mbr (the default), partition (installs the boot loader on the first sector of the partition containing the kernel), or none (do not install the boot loader).

--password=

If using GRUB, sets the GRUB boot loader password. This should be used to restrict access to the GRUB shell, where arbitrary kernel options can be passed.

--iscrypted=

If given, the password specified by --password= is already encrypted and should be passed to the bootloader configuration without additional modification.

--md5pass=

If using GRUB, similar to --password= except the password should already be encrypted.

--upgrade

Upgrade the existing boot loader configuration, preserving the old entries. This option is only available for upgrades.

--timeout=<secs>

Specify the number of seconds before the bootloader times out and boots the default option.

--default=

Sets the default boot image in the bootloader configuration.

--extlinux

Use the extlinux bootloader instead of GRUB. This option only works on machines that are supported by extlinux.

btrfs

(Added in anaconda-17.3)

Defines a BTRFS volume or subvolume. This command is of the form:

btrfs <mntpoint> --data=<level> --metadata=<level> --label=<label> <partitions*>

for volumes and of the form:

btrfs <mntpoint> --subvol --name=<path> <parent>

for subvolumes.

The <partitions*> (which denotes that multiple partitions can be listed) lists the BTRFS identifiers to add to the BTRFS volume. For subvolumes, <parent> should be the identifier of the subvolume's parent volume.

<mntpoint>

Location where the file system is mounted.

--data=

RAID level to use (0, 1, 10) for filesystem data. Optional. This option has no meaning for subvolumes.

--metadata=

RAID level to use (0, 1, 10) for filesystem/volume metadata. Optional. This option has no meaning for subvolumes.

--label=

Specify the label to give to the filesystem to be made. If the given label is already in use by another filesystem, a new label will be created. This option has no meaning for subvolumes.

--noformat

Use an existing BTRFS volume and do not reformat the filesystem. This option has no meaning for subvolumes.

--useexisting

Same as --noformat, above. This option has no meaning for subvolumes.

The following example shows how to create a BTRFS volume from member partitions on three disks with subvolumes for root and home. The main volume is not mounted or used directly in this example -- only the root and home subvolumes.

part btrfs.01 --size=6000 --ondisk=sda
part btrfs.02 --size=6000 --ondisk=sdb
part btrfs.03 --size=6000 --ondisk=sdc

btrfs none --data=0 --metadata=1 --label=f17 btrfs.01 btrfs.02 btrfs.03
btrfs / --subvol --name=root LABEL=f17
btrfs /home --subvol --name=home f17

clearpart

Removes partitions from the system, prior to creation of new partitions. By default, no partitions are removed.

If the clearpart command is used, then the --onpart command cannot be used on a logical partition.

--all

Erases all partitions from the system.

--drives=

Specifies which drives to clear partitions from. For example, the following clears the partitions on the first two drives on the primary IDE controller:

clearpart --all --drives=sda,sdb

--list=

Specifies which partitions to clear. If given, this supercedes any of the --all and --linux options. This can be across different drives:

clearpart --list=sda2,sda3,sdb1

--initlabel

Initializes the disk label to the default for your architecture (for example msdos for x86 and gpt for Itanium). This is only meaningful in combination with the '--all' option.

--linux

Erases all Linux partitions.

--none (default)

Do not remove any partitions.

cmdline

Perform the installation in a completely non-interactive command line mode. Any prompts for interaction will halt the install. This mode is useful on S/390 systems with the x3270 console.

device

On most PCI systems, the installation program will autoprobe for Ethernet and SCSI cards properly. On older systems and some PCI systems, however, kickstart needs a hint to find the proper devices. The device command, which tells the installation program to install extra modules, is in this format:

device <moduleName> --opts=<options>

<moduleName>

Replace with the name of the kernel module which should be installed.

--opts=

Options to pass to the kernel module. For example:

--opts="aic152x=0x340 io=11"

dmraid

dmraid --name= --dev=

driverdisk

Driver diskettes can be used during kickstart installations. You need to copy the driver disk's contents to the root directory of a partition on the system's hard drive. Then you need to use the driverdisk command to tell the installation program where to look for the driver disk.

driverdisk <partition>|--source=<url>|--biospart=<part>

<partition>

Partition containing the driver disk.

--source=<url>

Specify a URL for the driver disk. NFS locations can be given with nfs:host:/path/to/img.

--biospart=<part>

BIOS partition containing the driver disk (such as 82p2).

fcoe

firewall

This option corresponds to the Firewall Configuration screen in the installation program:

firewall --enabled|--disabled <device> [options]

--enabled or --enable

Reject incoming connections that are not in response to outbound requests, such as DNS replies or DHCP requests. If access to services running on this machine is needed, you can choose to allow specific services through the firewall.

--disabled or --disable

Do not configure any iptables rules.

--trust=

Listing a device here, such as eth0, allows all traffic coming from that device to go through the firewall. To list more than one device, use --trust eth0 --trust eth1. Do NOT use a comma-separated format such as --trust eth0, eth1.

<incoming>

Replace with none or more of the following to allow the specified services through the firewall.

--ssh - The ssh option is enabled by default, regardless of the presence of this flag.

--smtp

--http

--ftp

--port=

You can specify that ports be allowed through the firewall using the port:protocol format. You can also specify ports numerically. Multiple ports can be combined into one option as long as they are separated by commas. For example:

firewall --port=imap:tcp,1234:ucp,47

--service=

This option provides a higher-level way to allow services through the firewall. Some services (like cups, avahi, etc.) require multiple ports to be open in order for the service to work. You could specify each individual service with the --port option, or specify --service= and open them all at once. Valid options are anything recognized by the firewall-offline-cmd program in the firewalld package.

firstboot

Determine whether the Setup Agent starts the first time the system is booted. If enabled, the firstboot package must be installed. If not specified, firstboot is disabled by default.

--enable or --enabled

The Setup Agent is started the first time the system boots.

--disable or --disabled

The Setup Agent is not started the first time the system boots.

--reconfig

Enable the Setup Agent to start at boot time in reconfiguration mode. This mode enables the language, mouse, keyboard, root password, security level, time zone, and networking configuration options in addition to the default ones.

group

Creates a new user group on the system. If a group with the given name or GID already exists, this command will fail. In addition, the user command can be used to create a new group for the newly created user.

group --name=<name> [--gid=<gid>]

--name=

Provides the name of the new group.

--gid=

The group's GID. If not provided, this defaults to the next available non-system GID.

graphical

Perform the kickstart installation in graphical mode. This is the default.

halt

At the end of installation, display a message and wait for the user to press a key before rebooting. This is the default action.

ignoredisk

Controls anaconda's access to disks attached to the system. Only one of the following two options may be used.

ignoredisk --drives=[disk1,disk2,...]

Specifies those disks that anaconda should not touch when partitioning, formatting, and clearing.

ignoredisk --only-use=[disk1,disk2,...]

Specifies the opposite - only disks listed here will be used during installation.

ignoredisk --interactive

Allow the user manually navigate the advanced storage screen.

install

Tells the system to install a fresh system rather than upgrade an existing system. This is the default mode. For installation, you must specify the type of installation from one of cdrom, harddrive, nfs, or url (for ftp or http installations). The install command and the installation method command must be on separate lines.

cdrom

cdrom

Install from the first CD-ROM/DVD drive on the system.

harddrive

harddrive [--biospart=<bios partition> | --partition=<partition>] [--dir=<directory>]

Install from a directory of ISO images on a local drive, which must be either vfat or ext2. In addition to this directory, you must also provide the install.img in some way. You can either do this by booting off the boot.iso or by creating an images/ directory in the same directory as the ISO images and placing install.img in there.

--biospart=

BIOS partition to install from (such as 82p2).

--partition=

Partition to install from (such as, sdb2).

--dir=

Directory containing both the ISO images and the images/install.img. For example:

harddrive --partition=hdb2 --dir=/tmp/install-tree

liveimg

liveimg --url=<url> [--proxy=<proxyurl>] [--checksum=<sha256>] [--noverifyssl]

Install a disk image instead of packages. The image can be the squashfs.img from a Live iso, or any filesystem mountable by the install media (eg. ext4). Anaconda expects the image to contain utilities it needs to complete the system install so the best way to create one is to use livemedia-creator to make the disk image. If the image contains /LiveOS/*.img (this is how squashfs.img is structured) the first *img file inside LiveOS will be mounted and used to install the target system.

--url=

The URL to install from. http, https, ftp and file are supported.

--proxy=[protocol://][username[:password]@]host[:port]

Specify an HTTP/HTTPS/FTP proxy to use while performing the install. The various parts of the argument act like you would expect.

--checksum=

Optional sha256 checksum of the image file

--noverifyssl

For a tree on a HTTPS server do not check the server's certificate with what well-known CA validate and do not check the server's hostname matches the certificate's domain name.

nfs

nfs --server=<hostname> --dir=<directory> [--opts=<nfs options>]

Install from the NFS server specified. This can either be an exploded installation tree or a directory of ISO images. In the latter case, the install.img must also be provided subject to the same rules as with the harddrive installation method described above.

--server=

Server from which to install (hostname or IP).

--dir=

Directory containing the Packages/ directory of the installation tree. If doing an ISO install, this directory must also contain images/install.img.

--opts=

Mount options to use for mounting the NFS export. Any options that can be specified in /etc/fstab for an NFS mount are allowed. The options are listed in the nfs(5) man page. Multiple options are separated with a comma.

For example:

nfs --server=nfsserver.example.com --dir=/tmp/install-tree

url

url --url=<url>|--mirrorlist=<url> [--proxy=<proxy url>] [--noverifyssl]

Install from an installation tree on a remote server via FTP or HTTP.

--url=

The URL to install from. Variable substitution is done for $releasever and $basearch in the url (added in F19).

--mirrorlist=

The mirror URL to install from. Variable substitution is done for $releasever and $basearch in the url (added in F19).

--proxy=[protocol://][username[:password]@]host[:port]

Specify an HTTP/HTTPS/FTP proxy to use while performing the install. The various parts of the argument act like you would expect.

--noverifyssl

For a tree on a HTTPS server do not check the server's certificate with what well-known CA validate and do not check the server's hostname matches the certificate's domain name.

iscsi

Specifies additional iSCSI storage to be attached during installation. If you use the iscsi parameter, you must also assign a name to the iSCSI node, using the iscsiname parameter. The iscsiname parameter must appear before the iscsi parameter in the kickstart file.

iscsi --ipaddr= [options]

We recommend that wherever possible you configure iSCSI storage in the system BIOS or firmware (iBFT for Intel systems) rather than use the iscsi parameter. *Anaconda* automatically detects and uses disks configured in BIOS or firmware and no special configuration is necessary in the kickstart file.

If you must use the iscsi parameter, ensure that networking is activated at the beginning of the installation, and that the iscsi parameter appears in the kickstart file before you refer to iSCSI disks with parameters such as clearpart or ignoredisk.

--ipaddr= (mandatory)

The IP address of the target to connect to.

--port=

The port number to connect to (default, --port=3260).

--target=

The target iqn.

--iface=

Bind connection to specific network interface instead of using the default one determined by network layer. Once used, it must be specified for all iscsi commands.

--user=

The username required to authenticate with the target.

--password=

The password that corresponds with the username specified for the target.

--reverse-user=

The username required to authenticate with the initiator from a target that uses reverse CHAP authentication.

--reverse-password=

The password that corresponds with the username specified for the initiator.

iscsiname

Assigns an initiator name to the computer. If you use the iscsi parameter in your kickstart file, this parameter is mandatory, and you must specify iscsiname in the kickstart file before you specify iscsi.

iscsiname <iqn>

keyboard

This required command sets system keyboard type. See the documentation of --vckeymap option and the tip at the end of this section for a guide how to get values accepted by this command.

Starting with Fedora 18 the keyboard command has three new options:

keyboard [--vckeymap=<keymap>] [--xlayouts=<layout1>,<layout2>,...,<layoutN>] [--switch=<option1>...<optionN>] [arg]

Either --vckeymap or --xlayouts must be used.

Alternatively, use the older format, arg, which is still supported. arg can be an X layout or VConsole keymap name.

Missing values will be automatically converted from the given one(s).

--vckeymap=<keymap>

Specify VConsole keymap that should be used. <keymap> is a keymap name which is the same as the filename under /usr/lib/kbd/keymaps/ without the ".map.gz" extension.

--xlayouts=<layout1>,<layout2>,...,<layoutN>

Specify a list of X layouts that should be used (comma-separated list without spaces).

Accepts the same values as setxkbmap(1), but uses either the layout format (such as cz) or the 'layout (variant)' format (such as 'cz (qwerty)').

For example:

keyboard --xlayouts=cz,'cz (qwerty)'

--switch=<option1>,...,<optionN>

Specify a list of layout switching options that should be used (comma-separated list without spaces).

Accepts the same values as setxkbmap(1) for layout switching.

For example

keyboard --xlayouts=cz,'cz (qwerty)' --switch=grp:alt_shift_toggle

If you know only the description of the layout (e.g. Czech (qwerty)), you can use http://vpodzime.fedorapeople.org/layouts_list.py to list all available layouts and find the one you want to use. The string in square brackets is the valid layout specification as Anaconda accepts it. The same goes for switching options and http://vpodzime.fedorapeople.org/switching_list.py (both scripts need package libxklavier installed in version >= 5.1-1)

lang

lang <id>

This required command sets the language to use during installation and the default language to use on the installed system to <id>. This can be the same as any recognized setting for the $LANG environment variable, though not all languages are supported during installation.

Certain languages (mainly Chinese, Japanese, Korean, and Indic languages) are not supported during text mode installation. If one of these languages is specified using the lang command, installation will continue in English though the running system will have the specified langauge by default.

The file /usr/share/system-config-language/locale-list provides a list the valid language codes in the first column of each line and is part of the system-config-languages package.

logvol

Create a logical volume for Logical Volume Management (LVM).

logvol <mntpoint> --vgname=<name> --size=<size> --name=<name> <options>

--noformat

Use an existing logical volume and do not format it.

--useexisting

Use an existing logical volume and reformat it.

--fstype=

Sets the file system type for the logical volume. Valid values include ext4, ext3, ext2, btrfs, swap, and vfat. Other filesystems may be valid depending on command line arguments passed to anaconda to enable other filesystems. Btrfs is a experimental filesystem. Do take regular backups if you are using it.

--fsoptions=

Specifies a free form string of options to be used when mounting the filesystem. This string will be copied into the /etc/fstab file of the installed system and should be enclosed in quotes.

--grow

Tells the logical volume to grow to fill available space (if any), or up to the maximum size setting. Note that --grow is not supported for logical volumes containing a RAID volume on top of them.

--maxsize=

The maximum size in megabytes when the logical volume is set to grow. Specify an integer value here, and do not append the number with MB.

--recommended

Determine the size of the logical volume automatically.

--percent

Specify the size of the logical volume as a percentage of available space in the volume group. Without the above --grow option, this may not work.

--encrypted

Specify that this logical volume should be encrypted.

--passphrase=

Specify the passphrase to use when encrypting this logical volume. Without the above --encrypted option, this option does nothing. If no passphrase is specified, the default system-wide one is used, or the installer will stop and prompt if there is no default.

--escrowcert=<url>

Load an X.509 certificate from <url>. Store the data encryption key of this logical volume, encrypted using the certificate, as a file in /root. Only relevant if --encrypted is specified as well.

--backuppassphrase

Only relevant if --escrowcert is specified as well. In addition to storing the data encryption key, generate a random passphrase and add it to this logical volume. Then store the passphrase, encrypted using the certificate specified by --escrowcert, as a file in /root. If more than one LUKS volume uses --backuppassphrase, the same passphrase will be used for all such volumes.

Create the partition first, create the logical volume group, and then create the logical volume. For example:

part pv.01 --size 3000
volgroup myvg pv.01
logvol / --vgname=myvg --size=2000 --name=rootvol

logging

This command controls the error logging of anaconda during installation. It has no effect on the installed system.

--host=

Send logging information to the given remote host, which must be running a syslogd process configured to accept remote logging.

--port=

If the remote syslogd process uses a port other than the default, it may be specified with this option.

--level=

One of debug, info, warning, error, or critical.

Specify the minimum level of messages that appear on tty3. All messages will still be sent to the log file regardless of this level, however.

mediacheck

If given, this will force anaconda to run mediacheck on the installation media. This command requires that installs be attended, so it is disabled by default.

monitor

If the monitor command is not given, anaconda will use X to automatically detect your monitor settings. Please try this before manually configuring your monitor.

--hsync=

Specifies the horizontal sync frequency of the monitor.

--monitor=

Use specified monitor; monitor name should be from the list of monitors in /usr/share/hwdata/MonitorsDB from the hwdata package. The list of monitors can also be found on the X Configuration screen of the Kickstart Configurator. This is ignored if --hsync or --vsync is provided. If no monitor information is provided, the installation program tries to probe for it automatically.

--noprobe

Do not probe the monitor.

--vsync=

Specifies the vertical sync frequency of the monitor.

multipath

multipath --name= --device= --rule=

network

Configures network information for target system and activates network devices in installer environment. Device of the first network command is activated if network is required, e.g. in case of network installation or using vnc. Activation of the device can be also explicitly required by --activate option. If the device has already been activated to get kickstart file (e.g. using configuration provided with boot options or entered in loader UI) it is re-activated with configuration from kickstart file.

In F15, the device of first network command is activated also in case of non-network installs, and device is not re-activated using kickstart configuration.

Additional devices configured in kickstart with network command can be activated in installer using --activate option (since F16).

--bootproto=[dhcp|bootp|static|ibft]

The default setting is dhcp. bootp and dhcp are treated the same.

The DHCP method uses a DHCP server system to obtain its networking configuration. As you might guess, the BOOTP method is similar, requiring a BOOTP server to supply the networking configuration.

The static method requires that you enter all the required networking information in the kickstart file. As the name implies, this information is static and will be used during and after the installation. The line for static networking is more complex, as you must include all network configuration information on one line. You must specify the IP address, netmask, gateway, and nameserver. For example: (the \ indicates that it is all one line):

network --bootproto=static --ip=10.0.2.15 \
--netmask=255.255.255.0 --gateway=10.0.2.254 \
--nameserver=10.0.2.1

If you use the static method, be aware of the following restriction:

• All static networking configuration information must be specified on one line; you cannot wrap lines using a backslash, for example.

ibft setting is for reading the configuration from iBFT table. It was added in F16.

--device=

Specifies device to be configured and/or activated with the network command. The device can be specified in the same ways as ksdevice boot option. For example:

network --bootproto=dhcp --device=eth0

For the first network command, if the option is not specified it defaults to 1) ksdevice boot option, 2) device activated to fetch kickstart, or 3) selection dialog in UI. For following network commands, the --device option is required.

--ip=

IP address for the interface.

--ipv6=

IPv6 address for the interface. This can be the static address in form <IPv6 address>[/<prefix length>], e.g. 3ffe:ffff:0:1::1/128 (if prefix is omitted 64 is assumed), "auto" for address assignment based on automatic neighbor discovery, or "dhcp" to use the DHCPv6 protocol.

--gateway=

Default gateway, as an IPv4 or IPv6 address.

--nodefroute

Prevents grabbing of the default route by the device. It can be useful when activating additional devices in installer using --activate option. Since F16.

--nameserver=

Primary nameserver, as an IP address. Multiple nameservers must be comma separated.

--nodns

Do not configure any DNS server.

--netmask=

Netmask for the installed system.

--hostname=

Hostname for the installed system.

--ethtool=

Specifies additional low-level settings for the network device which will be passed to the ethtool program.

--essid=

The network ID for wireless networks.

--wepkey=

The WEP encryption key for wireless networks.

--wpakey=

The WPA encryption key for wireless networks (since F16).

--onboot=

Whether or not to enable the device a boot time.

--dhcpclass=

The DHCP class.

--mtu=

The MTU of the device.

--noipv4

Disable IPv4 on this device.

--noipv6

Disable IPv6 on this device.

part or partition

Creates a partition on the system. This command is required for installs, and is ignored on upgrades.

If more than one Linux installation exists on the system on different partitions, the installation program prompts the user and asks which installation to upgrade.

All partitions created will be formatted as part of the installation process unless --noformat and --onpart are used.

part <mntpoint>

The <mntpoint> is where the partition will be mounted and must be of one of the following forms:

/<path>

For example, /, /usr, /home

swap

The partition will be used as swap space.

To determine the size of the swap partition automatically, use the --recommended option. Starting with Fedora 18 the --hibernation option can be used to automatically determine the size of the swap partition big enough for hibernation.

raid.<id>

The partition will be used for software RAID (refer to raid).

pv.<id>

The partition will be used for LVM (refer to logvol).

--size=

The minimum partition size in megabytes. Specify an integer value here such as 500. Do not append the number with MB.

--grow

Tells the partition to grow to fill available space (if any), or up to the maximum size setting. Note that --grow is not supported for partitions containing a RAID volume on top of them.

--maxsize=

The maximum partition size in megabytes when the partition is set to grow. Specify an integer value here, and do not append the number with MB.

--noformat

Tells the installation program not to format the partition, for use with the --onpart command.

--onpart= or --usepart=

Put the partition on an already existing device. Use "--onpart=LABEL=name" or "--onpart=UUID=name" to specify a partition by label or uuid respectively.

Anaconda may create partitions in any particular order, so it is safer to use labels than absolute partition names.

--ondisk= or --ondrive=

Forces the partition to be created on a particular disk.

--asprimary

Forces automatic allocation of the partition as a primary partition or the partitioning will fail.

--fsprofile=

Specifies a usage type to be passed to the program that makes a filesystem on this partition. A usage type defines a variety of tuning parameters to be used when making a filesystem. For this option to work, the filesystem must support the concept of usage types and there must be a configuration file that lists valid types. For ext2/3/4, this configuration file is /etc/mke2fs.conf.

--fstype=

Sets the file system type for the partition. Valid values include ext4, ext3, ext2, btrfs, swap, and vfat. Other filesystems may be valid depending on command line arguments passed to anaconda to enable other filesystems.

--fsoptions=

Specifies a free form string of options to be used when mounting the filesystem. This string will be copied into the /etc/fstab file of the installed system and should be enclosed in quotes.

--label=

Specify the label to give to the filesystem to be made on the partition. If the given label is already in use by another filesystem, a new label will be created for this partition.

--recommended

Determine the size of the partition automatically.

--onbiosdisk=

Forces the partition to be created on a particular disk as discovered by the BIOS.

--encrypted

Specify that this partition should be encrypted.

--passphrase=

Specify the passphrase to use when encrypting this partition. Without the above --encrypted option, this option does nothing. If no passphrase is specified, the default system-wide one is used, or the installer will stop and prompt if there is no default.

--escrowcert=<url>

Load an X.509 certificate from <url>. Store the data encryption key of this partition, encrypted using the certificate, as a file in /root. Only relevant if --encrypted is specified as well.

--backuppassphrase

Only relevant if --escrowcert is specified as well. In addition to storing the data encryption key, generate a random passphrase and add it to this partition. Then store the passphrase, encrypted using the certificate specified by --escrowcert, as a file in /root. If more than one LUKS volume uses --backuppassphrase, the same passphrase will be used for all such volumes.

If partitioning fails for any reason, diagnostic messages will appear on virtual console 3.

poweroff

Turn off the machine after the installation is complete. Normally, kickstart displays a message and waits for the user to press a key before rebooting.

raid

Assembles a software RAID device. This command is of the form:

raid <mntpoint> --level=<level> --device=<mddevice> <partitions*>

<mntpoint>

Location where the RAID file system is mounted. If it is /, the RAID level must be 1 unless a boot partition (/boot) is present. If a boot partition is present, the /boot partition must be level 1 and the root (/) partition can be any of the available types. The <partitions*> (which denotes that multiple partitions can be listed) lists the RAID identifiers to add to the RAID array.

--level=

RAID level to use (0, 1, 4, 5, 6, or 10).

--device=

Name of the RAID device to use (such as md0 or md1). RAID devices range from md0 to md7, and each may only be used once.

--spares=

Specifies the number of spare drives allocated for the RAID array. Spare drives are used to rebuild the array in case of drive failure.

--fstype=

Sets the file system type for the RAID array. Valid values include ext4, ext3, ext2, btrfs, swap, and vfat. Other filesystems may be valid depending on command line arguments passed to anaconda to enable other filesystems.

--fsoptions=

Specifies a free form string of options to be used when mounting the filesystem. This string will be copied into the /etc/fstab file of the installed system and should be enclosed in quotes.

--label=

Specify the label to give to the filesystem to be made. If the given label is already in use by another filesystem, a new label will be created.

--noformat

Use an existing RAID device and do not format the RAID array.

--useexisting

Use an existing RAID device and reformat it.

--encrypted

Specify that this RAID device should be encrypted.

--passphrase=

Specify the passphrase to use when encrypting this RAID device. Without the above --encrypted option, this option does nothing. If no passphrase is specified, the default system-wide one is used, or the installer will stop and prompt if there is no default.

--escrowcert=<url>

Load an X.509 certificate from <url>. Store the data encryption key of this RAID device, encrypted using the certificate, as a file in /root. Only relevant if --encrypted is specified as well.

--backuppassphrase

Only relevant if --escrowcert is specified as well. In addition to storing the data encryption key, generate a random passphrase and add it to this RAID device. Then store the passphrase, encrypted using the certificate specified by --escrowcert, as a file in /root. If more than one LUKS volume uses --backuppassphrase, the same passphrase will be used for all such volumes.

The following example shows how to create a RAID level 1 partition for /, and a RAID level 5 for /usr, assuming there are three disks on the system. It also creates three swap partitions, one on each drive.

part raid.01 --size=6000 --ondisk=sda
part raid.02 --size=6000 --ondisk=sdb
part raid.03 --size=6000 --ondisk=sdc

part swap1 --size=512 --ondisk=sda
part swap2 --size=512 --ondisk=sdb
part swap3 --size=512 --ondisk=sdc

part raid.11 --size=6000 --ondisk=sda
part raid.12 --size=6000 --ondisk=sdb
part raid.13 --size=6000 --ondisk=sdc

raid / --level=1 --device=md0 raid.01 raid.02 raid.03
raid /usr --level=5 --device=md1 raid.11 raid.12 raid.13

realm

Join an Active Directory of FreeIPA domain.

realm join <domain.example.com>

--computer-ou=

The distinguished name of an organizational unit to create the computer account. The exact format of the distinguished name depends on the client software and membership software. You can usually omit the root DSE portion of distinguished name.

--no-password

Perform the join automatically without a password.

--one-time-password=

Perform the join using a one time password specified on the command line. This is not possible with all types of realms.

--client-software=

Only join realms for which we can use the given client software. Possible values include sssd or winbind. Not all values are supported for all realms. By default the client software is automatically selected.

--server-software=

Only join realms which run the given server software. Possible values include active-directory or freeipa.

--membership-software=

The software to use when joining to the realm. Possible values include samba or adcli. Not all values are supported for all realms. By default the membership software is automatically selected.

realm join --one-time-password=12345 DC.EXAMPLE.COM

reboot

Reboot after the installation is complete. Normally, kickstart displays a message and waits for the user to press a key before rebooting.

--eject

Attempt to eject CD or DVD media before rebooting.

repo

Configures additional yum repositories that may be used as sources for package installation. Multiple repo lines may be specified. By default, anaconda has a configured set of repos taken from /etc/anaconda.repos.d plus a special Installation Repo in the case of a media install. The exact set of repos in this directory changes from release to release and cannot be listed here. There will likely always be a repo named "updates".

Note: If you want to enable one of the repos in /etc/anaconda.repos.d that is disabled by default (like "updates"), you should use --name=<repoid> but none of the other options. anaconda will look for a repo by this name automatically. Providing a baseurl or mirrorlist URL will result in anaconda attempting to add another repo by the same name, which will cause a conflicting repo error.

repo --name=<name> [--baseurl=<url>|--mirrorlist=<url>] [options]

--name=

The repo id. This option is required. If a repo has a name that conflicts with a previously added one, the new repo will be ignored. Because anaconda has a populated list of repos when it starts, this means that users cannot create new repos that override these names. Please check /etc/anaconda.repos.d from the operating system you wish to install to see what names are not available.

--baseurl=

The URL for the repository. The variables that may be used in yum repo config files are not supported here. You may use one of either this option or --mirrorlist, not both. If an NFS repository is specified, it should be of the form nfs://host:/path/to/repo. Note that there is a colon after the host--Anaconda passes everything after "nfs://" directly to the mount command instead of parsing URLs according to RFC 2224. Variable substitution is done for $releasever and $basearch in the url (added in F19).

--mirrorlist=

The URL pointing at a list of mirrors for the repository. The variables that may be used in yum repo config files are not supported here. You may use one of either this option or --baseurl, not both. Variable substitution is done for $releasever and $basearch in the url (added in F19).

--cost=

An integer value to assign a cost to this repository. If multiple repositories provide the same packages, this number will be used to prioritize which repository will be used before another. Repositories with a lower cost take priority over repositories with higher cost.

--excludepkgs=

A comma-separated list of package names and globs that must not be pulled from this repository. This is useful if multiple repositories provide the same package and you want to make sure it comes from a particular repository.

--includepkgs=

A comma-separated list of package names and globs that must be pulled from this repository. This is useful if multiple repositories provide the same package and you want to make sure it comes from this repository.

--proxy=[protocol://][username[:password]@]host[:port]

Specify an HTTP/HTTPS/FTP proxy to use just for this repository. This setting does not affect any other repositories, nor how the install.img is fetched on HTTP installs. The various parts of the argument act like you would expect.

--ignoregroups=true

This option is used when composing installation trees and has no effect on the installation process itself. It tells the compose tools to not look at the package group information when mirroring trees so as to avoid mirroring large amounts of unnecessary data.

--noverifyssl

For a https repo do not check the server's certificate with what well-known CA validate and do not check the server's hostname matches the certificate's domain name.

rescue

Automatically enter the installer's rescue mode. This gives you a chance to repair the system should something catastrophic happen.

rescue [--nomount|--romount]

--nomount|--romount]

Controls how the installed system is mounted in the rescue environment. By default, the installer will find your system and mount it in read-write mode, telling you where it has performed this mount. You may optionally choose to not mount anything or mount in read-only mode. Only one of these two options may be given at any one time.

rootpw

This required command sets the system's root password to the <password> argument.

rootpw [options] <password>

--iscrypted|--plaintext

If this is present, the password argument is assumed to already be encrypted. --plaintext has the opposite effect - the password argument is assumed to not be encrypted. To create an encrypted password you can use python: python -c 'import crypt; print(crypt.crypt("My Password", "$6$My Sault"))' This will generate sha512 crypt of your password using your provided salt.

--lock

If this is present, the root account is locked by default. That is, the root user will not be able to login from the console.

selinux

Sets the state of SELinux on the installed system. SELinux defaults to enforcing in anaconda.

selinux [--disabled|--enforcing|--permissive]

--disabled

If this is present, SELinux is disabled.

--enforcing

If this is present, SELinux is set to enforcing mode.

--permissive

If this is present, SELinux is enabled, but only logs things that would be denied in enforcing mode.

services

Modifies the default set of services that will run under the default runlevel. The services listed in the disabled list will be disabled before the services listed in the enabled list are enabled.

services [--disabled=<list>] [--enabled=<list>]

--disabled=

Disable the services given in the comma separated list.

--enabled=

Enable the services given in the comma separated list.

shutdown

At the end of installation, shut down the machine. This is the same as the poweroff command. Normally, kickstart displays a message and waits for the user to press a key before rebooting.

sshpw

The installer can start up ssh to provide for interactivity and inspection, just like it can with telnet. The "sshd" option must be specified on the kernel command-line for Anaconda to start an ssh daemon. The sshpw command is used to control the accounts created in the installation environment that may be remotely logged into. For each instance of this command given, a user will be created. These users will not be created on the final system - they only exist for use while the installer is running.

Note that by default, root has a blank password. If you don't want any user to be able to ssh in and have full access to your hardware, you must specify sshpw for username root. Also note that if Anaconda fails to parse the kickstart file, it will allow anyone to login as root and have full access to your hardware.

sshpw --username=<name> <password> [--iscrypted|--plaintext] [--lock]

--username=

Provides the name of the user. This option is required.

--iscrypted|--plaintext

If this is present, the password argument is assumed to already be encrypted. --plaintext has the opposite effect - the password argument is assumed to not be encrypted.

--lock

If this is present, the new user account is locked by default. That is, the user will not be able to login from the console.

skipx

If present, X is not configured on the installed system.

text

Perform the kickstart installation in text mode. Kickstart installations are performed in graphical mode by default.

timezone

This required command sets the system time zone to <timezone> which may be any of the time zones listed by timeconfig.

timezone [--utc] <timezone>

--utc

If present, the system assumes the hardware clock is set to UTC (Greenwich Mean) time.

To get the list of supported timezones, you can either run this script: http://vpodzime.fedorapeople.org/timezones_list.py or look at this list: http://vpodzime.fedorapeople.org/timezones_list.txt

Starting with Fedora 18 the timezone command has two new options:

timezone [--utc] [--nontp] [--ntpservers=<server1>,<server2>,...,<serverN>] <timezone>

--nontp

Disable automatic starting of NTP service.

--ntpservers=<server1>,<server2>,...,<serverN>

Specify a list of NTP servers to be used (comma-separated list with no spaces).

For example:

timezone --ntpservers=ntp.cesnet.cz,tik.nic.cz Europe/Prague

updates

Specify the location of an updates.img for use in installation. See anaconda-release-notes.txt for a description of how to make an updates.img.

updates [URL]

If present, the URL for an updates image.

If not present, anaconda will attempt to load from a floppy disk.

upgrade

Tells the system to upgrade an existing system rather than install a fresh system. You must specify one of cdrom, harddrive, nfs, or url (for ftp and http) as the location of the installation tree. Refer to install for details.

--root-device=<root> (optional)

On a system with multiple installs, this option specifies which filesystem holds the installation to be upgraded. This can be specified by device name, UUID=<uuid>, or LABEL=<fslabel> just like the harddrive command may be.

user

Creates a new user on the system.

user --name=<username> [--gecos=<string>] [--groups=<list>] [--homedir=<homedir>] [--password=<password>] [--iscrypted|--plaintext] [--lock] [--shell=<shell>] [--uid=<uid>]

--name=

Provides the name of the user. This option is required.

--gecos=

Provides the GECOS information for the user. This is a string of various system-specific fields separated by a comma. It is frequently used to specify the user's full name, office number, and the like. See man 5 passwd for more details.

--groups=

In addition to the default group, a comma separated list of group names the user should belong to.

--homedir=

The home directory for the user. If not provided, this defaults to /home/<username>.

--lock

If this is present, the new user account is locked by default. That is, the user will not be able to login from the console.

--password=

The new user's password. If not provided, the account will be locked by default.

If this is present, the password argument is assumed to already be encrypted. --plaintext has the opposite effect - the password argument is assumed to not be encrypted. To create an encrypted password you can use python: python -c 'import crypt; print(crypt.crypt("My Password", "$6$My Sault"))' This will generate sha512 crypt of your password using your provided salt.

--iscrypted|--plaintext

Is the password provided by --password already encrypted or not? --plaintext has the opposite effect - the password argument is assumed to not be encrypted.

--shell=

The user's login shell. If not provided, this defaults to the system default.

--uid=

The user's UID. If not provided, this defaults to the next available non-system UID.

vnc

Allows the graphical installation to be viewed remotely via VNC. This method is usually preferred over text mode, as there are some size and language limitations in text installs. With no options, this command will start a VNC server on the machine with no password and will print out the command that needs to be run to connect a remote machine.

vnc [--host=<hostname>] [--port=<port>] [--password=<password>]

--host=

Instead of starting a VNC server on the install machine, connect to the VNC viewer process listening on the given hostname.

--port=

Provide a port that the remote VNC viewer process is listening on. If not provided, anaconda will use the VNC default.

--password=

Set a password which must be provided to connect to the VNC session. This is optional, but recommended.

volgroup

Use to create a Logical Volume Management (LVM) group.

volgroup <name> <partitions*> <options>

<name>

Name given to the volume group. The <partitions*> (which denotes that multiple partitions can be listed) lists the identifiers to add to the volume group.

--noformat

Use an existing volume group.

--useexisting

Use an existing volume group.

--pesize=

Set the size of the physical extents.

--reserved-space=

Specify an amount of space to leave unused in a volume group, in megabytes. (new volume groups only)

--reserved-percent=

Specify a percentage of total volume group space to leave unused. (new volume groups only)

Create the partition first, create the logical volume group, and then create the logical volume. For example:

part pv.01 --size 3000
volgroup myvg pv.01
logvol / --vgname=myvg --size=2000 --name=rootvol

xconfig

Configures the X Window System. If this option is not given, anaconda will use X to attempt to automatically configure. Please try this before manually configuring your system.

--defaultdesktop=

Specify either GNOME or KDE to set the default desktop (assumes that GNOME Desktop Environment and/or KDE Desktop Environment has been installed through %packages).

--startxonboot

Use a graphical login on the installed system.

zerombr

If zerombr is specified, any disks whose formatting is unrecognized are initialized. This will destroy all of the contents of disks with invalid partition tables or other formatting unrecognizable to the installer. It is useful so that the installation program does not ask if it should initialize the disk label if installing to a brand new hard drive.

zfcp

--devnum=

--fcplun=

--wwpn=

%include

Use the %include /path/to/file or %include <url> command to include the contents of another file in the kickstart file as though the contents were at the location of the %include command in the kickstart file.

%ksappend

The %ksappend url directive is very similar to %include in that it is used to include the contents of additional files as though they were at the location of the %ksappend directive. The difference is in when the two directives are processed. %ksappend is processed in an initial pass, before any other part of the kickstart file. Then, this expanded kickstart file is passed to the rest of anaconda where all %pre scripts are handled, and then finally the rest of the kickstart file is processed in order, which includes %include directives.

Thus, %ksappend provides a way to include a file containing %pre scripts, while %include does not.

Chapter 3. Package Selection

Use the %packages command to begin a kickstart file section that lists the packages you would like to install (this is for installations only, as package selection during upgrades is not supported).

Packages can be specified by group or by individual package name. The installation program defines several groups that contain related packages. Refer to the repodata/*comps.xml file on the first CD-ROM for a list of groups. Each group has an id, user visibility value, name, description, and package list. In the package list, the packages marked as mandatory are always installed if the group is selected, the packages marked default are selected by default if the group is selected, and the packages marked optional must be specifically selected even if the group is selected to be installed.

In most cases, it is only necessary to list the desired groups and not individual packages. Note that the Core group is always selected by default, so it is not necessary to specify it in the %packages section.

The %packages section is required to be closed with %end. Also, multiple %packages sections may be given. This may be handy if the kickstart file is used as a template and pulls in various other files with the %include mechanism.

Here is an example %packages selection:

%packages
@X Window System
@GNOME Desktop Environment
@Graphical Internet
@Sound and Video
dhcp
%end

As you can see, groups are specified, one to a line, starting with an @ symbol followed by the full group name as given in the comps.xml file. Groups can also be specified using the id for the group, such as gnome-desktop. Specify individual packages with no additional characters (the dhcp line in the example above is an individual package).

Additionally, individual packages may be specified using globs. For instance:

%packages
vim*
kde-i18n-*
%end

This would install all packages whose names start with "vim" or "kde-i18n-".

You can also specify which packages not to install from the default package list:

%packages
-autofs
%end

The following options are available for the %packages option:

--default

Install the default package set. This corresponds to the package set that would be installed if no other selections were made on the package customization screen during an interactive install.

--excludedocs

Do not install any of the documentation from any packages. For the most part, this means files in /usr/share/doc* will not get installed though it could mean other files as well, depending on how the package was built.

--ignoremissing

Ignore any packages or groups specified in the packages section that are not found in any configured repository. The default behavior is to halt the installation and ask the user if the installation should be aborted or continued. This option allows fully automated installation even in the error case. It is used as follows:

%packages --ignoremissing

--instLangs=

Specify the list of languages that should be installed. This is different from the package group level selections, though. This option does not specify what package groups should be installed. Instead, it controls which translation files from individual packages should be installed by setting RPM macros. Note: this option is not supported by anaconda at the moment, but is recognized by pykickstart for use in such tools as livecd-creator.

--multilib

Enable yum's "all" multilib_policy as opposed to the default of "best".

In addition, group lines in the %packages section can take options as well:

--nodefaults

Only install the group's mandatory packages, not the default selections.

--optional

In addition to the mandatory and default packages, also install the optional packages. This means all packages in the group will be installed.

Chapter 4. Pre-installation Script

You can add commands to run on the system immediately after the ks.cfg has been parsed and the lang, keyboard, and url options have been processed. This section must be at the end of the kickstart file (after the commands) and must start with the %pre command. You can access the network in the %pre section; however, name service has not been configured at this point, so only IP addresses will work.

Preinstallation scripts are required to be closed with %end.

If your script spawns a daemon process, you must make sure to close stdout and stderr. Doing so is standard procedure for creating daemons. If you do not close these file descriptors, the installation will appear hung as anaconda waits for an EOF from the script.

Note that the pre-install script is not run in the chroot environment.

--interpreter /usr/bin/python

Allows you to specify a different scripting language, such as Python. Replace /usr/bin/python with the scripting language of your choice.

--erroronfail

If the pre-installation script fails, this option will cause an error dialog to be displayed and will halt installation. The error message will direct you to where the cause of the failure is logged.

--log=

Log all messages from the script to the given log file.

Example

Here is an example %pre section:

%pre
#!/bin/bash
hds=""
mymedia=""

for file in /sys/block/sd*; do
hds="$hds $(basename $file)"
done

set $hds
numhd=$(echo $#)

drive1=$(echo $hds | cut -d' ' -f1)
drive2=$(echo $hds | cut -d' ' -f2)


if [ $numhd == "2" ]  ; then
echo "#partitioning scheme generated in %pre for 2 drives" > /tmp/part-include
echo "clearpart --all" >> /tmp/part-include
echo "part /boot --fstype ext4 --size 512 --ondisk sda" >> /tmp/part-include
echo "part / --fstype ext4 --size 10000 --grow --ondisk sda" >> /tmp/part-include
echo "part swap --recommended --ondisk $drive1" >> /tmp/part-include
echo "part /home --fstype ext4 --size 10000 --grow --ondisk sdb" >> /tmp/part-include
else
echo "#partitioning scheme generated in %pre for 1 drive" > /tmp/part-include
echo "clearpart --all" >> /tmp/part-include
echo "part /boot --fstype ext4 --size 521" >> /tmp/part-include
echo "part swap --recommended" >> /tmp/part-include
echo "part / --fstype ext4 --size 2048" >> /tmp/part-include
echo "part /home --fstype ext4 --size 2048 --grow" >> /tmp/part-include
fi
%end

This script determines the number of hard drives in the system and writes a text file with a different partitioning scheme depending on whether it has one or two drives. Instead of having a set of partitioning commands in the kickstart file, include the line:

%include /tmp/part-include

The partitioning commands selected in the script will be used.

Chapter 5. Post-installation Script

You have the option of adding commands to run on the system once the installation is complete. This section must be at the end of the kickstart file and must start with the %post command. This section is useful for functions such as installing additional software and configuring an additional nameserver.

You may have more than one %post section, which can be useful for cases where some post-installation scripts need to be run in the chroot and others that need access outside the chroot.

Each %post section is required to be closed with a corresponding %end.

If you configured the network with static IP information, including a nameserver, you can access the network and resolve IP addresses in the %post section. If you configured the network for DHCP, the /etc/resolv.conf file has not been completed when the installation executes the %post section. You can access the network, but you can not resolve IP addresses. Thus, if you are using DHCP, you must specify IP addresses in the %post section.

If your script spawns a daemon process, you must make sure to close stdout and stderr. Doing so is standard procedure for creating daemons. If you do not close these file descriptors, the installation will appear hung as anaconda waits for an EOF from the script.

The post-install script is run in a chroot environment; therefore, performing tasks such as copying scripts or RPMs from the installation media will not work.

--nochroot

Allows you to specify commands that you would like to run outside of the chroot environment.

--interpreter /usr/bin/python

Allows you to specify a different scripting language, such as Python. Replace /usr/bin/python with the scripting language of your choice.

--erroronfail

If the post-installation script fails, this option will cause an error dialog to be displayed and will halt installation. The error message will direct you to where the cause of the failure is logged.

--log=

Log all messages from the script to the given log file.

Examples

Run a script named runme from an NFS share:

%post
mkdir /mnt/temp
mount 10.10.0.2:/usr/new-machines /mnt/temp
open -s -w -- /mnt/temp/runme
umount /mnt/temp
%end

Copy the file /etc/resolv.conf to the file system that was just installed:

%post --nochroot
cp /etc/resolv.conf /mnt/sysimage/etc/resolv.conf
%end

If your kickstart is being interpreted by the livecd-creator tool, you should replace /mnt/sysimage above with $INSTALL_ROOT.

Chapter 6. Making the Kickstart File Available

A kickstart file must be placed in one of the following locations:

• On a boot diskette

• On a boot CD-ROM

• On a network

Normally a kickstart file is copied to the boot diskette, or made available on the network. The network-based approach is most commonly used, as most kickstart installations tend to be performed on networked computers.

Let us take a more in-depth look at where the kickstart file may be placed.

Creating a Kickstart Boot Diskette

To perform a diskette-based kickstart installation, the kickstart file must be named ks.cfg and must be located in the boot diskette's top-level directory. Refer to the section Making an Installation Boot Diskette in the Red Hat Enterprise Linux Installation Guide for instruction on creating a boot diskette. Because the boot diskettes are in MS-DOS format, it is easy to copy the kickstart file under Linux using the mcopy command:

mcopy ks.cfg a:

Alternatively, you can use Windows to copy the file. You can also mount the MS-DOS boot diskette in Linux with the file system type vfat and use the cp command to copy the file on the diskette.

Creating a Kickstart Boot CD-ROM

To perform a CD-ROM-based kickstart installation, the kickstart file must be named ks.cfg and must be located in the boot CD-ROM's top-level directory. Since a CD-ROM is read-only, the file must be added to the directory used to create the image that is written to the CD-ROM. Refer to the Making an Installation Boot CD-ROM section in the Red Hat Enterprise Linux Installation Guide for instruction on creating a boot CD-ROM; however, before making the file.iso image file, copy the ks.cfg kickstart file to the isolinux/ directory.

Making the Kickstart File Available on the Network

Network installations using kickstart are quite common, because system administrators can easily automate the installation on many networked computers quickly and painlessly. In general, the approach most commonly used is for the administrator to have both a BOOTP/DHCP server and an NFS server on the local network. The BOOTP/DHCP server is used to give the client system its networking information, while the actual files used during the installation are served by the NFS server. Often, these two servers run on the same physical machine, but they are not required to.

To perform a network-based kickstart installation, you must have a BOOTP/DHCP server on your network, and it must include configuration information for the machine on which you are attempting to install Fedora or Red Hat Enterprise Linux. The BOOTP/DHCP server will provide the client with its networking information as well as the location of the kickstart file.

If a kickstart file is specified by the BOOTP/DHCP server, the client system will attempt an NFS mount of the file's path, and will copy the specified file to the client, using it as the kickstart file. The exact settings required vary depending on the BOOTP/DHCP server you use.

Here is an example of a line from the dhcpd.conf file for the DHCP server:

filename "/usr/new-machine/kickstart/";
server-name "blarg.redhat.com";

Note that you should replace the value after filename with the name of the kickstart file (or the directory in which the kickstart file resides) and the value after server-name with the NFS server name.

If the filename returned by the BOOTP/DHCP server ends with a slash ("/"), then it is interpreted as a path only. In this case, the client system mounts that path using NFS, and searches for a particular file. The filename the client searches for is:

<ip-addr>-kickstart

The <ip-addr> section of the filename should be replaced with the client's IP address in dotted decimal notation. For example, the filename for a computer with an IP address of 10.10.0.1 would be 10.10.0.1-kickstart.

Note that if you do not specify a server name, then the client system will attempt to use the server that answered the BOOTP/DHCP request as its NFS server. If you do not specify a path or filename, the client system will try to mount /kickstart from the BOOTP/DHCP server and will try to find the kickstart file using the same <ip-addr>-kickstart filename as described above.

HTTP Headers

When Anaconda requests the kickstart over the network it includes several custom HTTP headers:

X-Anaconda-Architecture: x86_64 indicates the architecture of the system being installed to.

X-Anaconda-System-Release: Fedora indicates the product name being installed.

There are also 2 optional headers, controlled by the kernel command line options kssendmac and kssendsn

Chapter 7. Making the Installation Tree Available

The kickstart installation needs to access an installation tree. An installation tree is a copy of the binary Fedora or Red Hat Enterprise Linux CD-ROMs with the same directory structure.

If you are performing a CD-based installation, insert the Fedora or Red Hat Enterprise Linux CD-ROM #1 into the computer before starting the kickstart installation.

If you are performing a hard-drive installation, make sure the ISO images of the binary Fedora or Red Hat Enterprise Linux CD-ROMs are on a hard drive in the computer.

If you are performing a network-based (NFS, FTP, or HTTP) installation, you must make the installation tree available over the network. Refer to the Preparing for a Network Installation section of the Red Hat Enterprise Linux Installation Guide for details.

Chapter 8. Starting a Kickstart Installation

To begin a kickstart installation, you must boot the system from a Fedora or Red Hat Enterprise Linux boot diskette, Fedora or Red Hat Enterprise Linux boot CD-ROM, or the Fedora or Red Hat Enterprise Linux CD-ROM #1 and enter a special boot command at the boot prompt. In order to get to the boot prompt you must hit escape at the CD or DVD boot menu. In case you don't know what I'm talking about I took a screenshot. The installation program looks for a kickstart file if the ks command line argument is passed to the kernel.

Boot Diskette

If the kickstart file is located on a boot diskette as described in the Section called Creating a Kickstart Boot Diskette in Chapter 6, boot the system with the diskette in the drive, and enter the following command at the boot: prompt:

linux ks=floppy

CD-ROM #1 and Diskette

The linux ks=floppy command also works if the ks.cfg file is located on a vfat or ext2 file system on a diskette and you boot from the Fedora or Red Hat Enterprise Linux CD-ROM #1.

An alternate boot command is to boot off the Fedora or Red Hat Enterprise Linux CD-ROM #1 and have the kickstart file on a vfat or ext2 file system on a diskette. To do so, enter the following command at the boot: prompt:

linux ks=hd:fd0:/ks.cfg

With Driver Disk

If you need to use a driver disk with kickstart, specify the dd option as well. For example, to boot off a boot diskette and use a driver disk, enter the following command at the boot: prompt:

linux ks=floppy dd

Boot CD-ROM

If the kickstart file is on a boot CD-ROM as described in the Section called Creating a Kickstart Boot CD-ROM in Chapter 6, insert the CD-ROM into the system, boot the system, and enter the following command at the boot: prompt (where ks.cfg is the name of the kickstart file):

linux ks=cdrom:<device>:/ks.cfg

Other kickstart options:

ks=nfs:<server>:/<path>

The installation program will look for the kickstart file on the NFS server <server>, as file <path>. The installation program will use DHCP to configure the Ethernet card. For example, if your NFS server is server.example.com and the kickstart file is in the NFS share /mydir/ks.cfg, the correct boot command would be ks=nfs:server.example.com:/mydir/ks.cfg.

ks=http://<server>/<path>

The installation program will look for the kickstart file on the HTTP server <server>, as file <path>. The installation program will use DHCP to configure the Ethernet card. For example, if your HTTP server is server.example.com and the kickstart file is in the HTTP directory /mydir/ks.cfg, the correct boot command would be ks=http://server.example.com/mydir/ks.cfg.

ks=floppy

The installation program looks for the file ks.cfg on a vfat or ext2 file system on the diskette in /dev/fd0.

ks=floppy:/<path>

The installation program will look for the kickstart file on the diskette in /dev/fd0, as file <path>.

ks=hd:<device>:/<file>

The installation program will mount the file system on <device> (which must be vfat or ext2), and look for the kickstart configuration file as <file> in that file system (for example, ks=hd:sda3:/mydir/ks.cfg).

ks=bd:<biosdev>:/<path>

The installation program will mount the file system on the specified partition on the specified BIOS device <biosdev> (for example, ks=bd:80p3:/mydir/ks.cfg). Note this does not work for BIOS RAID sets.

ks=file:/<file>

The installation program will try to read the file <file> from the file system; no mounts will be done. This is normally used if the kickstart file is already on the initrd image.

ks=cdrom:/<path> or in newer versions ks=cdrom:<cdrom device>:/<path>

The installation program will look for the kickstart file on CD-ROM, as file <path>.

ks

If ks is used alone, the installation program will configure the Ethernet card to use DHCP. The kickstart file is read from the "bootServer" from the DHCP response as if it is an NFS server sharing the kickstart file. By default, the bootServer is the same as the DHCP server. The name of the kickstart file is one of the following:

* If DHCP is specified and the bootfile begins with a /, the bootfile provided by DHCP is looked for on the NFS server.

* If DHCP is specified and the bootfile begins with something other then a /, the bootfile provided by DHCP is looked for in the /kickstart directory on the NFS server.

* If DHCP did not specify a bootfile, then the installation program tries to read the file /kickstart/1.2.3.4-kickstart, where 1.2.3.4 is the numeric IP address of the machine being installed.

ksdevice=<device>

The installation program will use this network device to connect to the network. For example, to start a kickstart installation with the kickstart file on an NFS server that is connected to the system through the eth1 device, use the command ks=nfs:<server>:/<path> ksdevice=eth1 at the boot: prompt. For more information, see Anaconda_Boot_Options.

Example Kickstart Script

Since I got tons of errors I thought I would share an example of a kickstart script that works. This also has an example of an lvm setup. I couldn't find a good example of an lvm anywhere else. I also added comments where I thought would help. Please modify if you think you have some other good examples.
