| =head1 NAME
| |
| | |
| livecd-iso-to-disk - installs bootable CD images on a USB storage devices.
| |
| | |
| =head1 SYNOPSIS
| |
| | |
| B<livecd-iso-to-disk> [--help] [--format] [--reset-mbr] [--efi] [--extra-kernel-args <args>] [--multi] [--livedir <dir>] [--compress] [--skip-compress] [--swap-size-mb <size>] [--xo] [--xo-no-home] [--noverify] [--skipcopy] [--overlay-size-mb <size>] [--copy-overlay] [--delete-home] [--home-size-mb <size>] [--copy-home] [--force] [--crypted-home] [--unencrypted-home] <isopath> <usbstick device>"
| |
| | |
| =head1 DESCRIPTION
| |
| | |
| B<livecd-iso-to-disk> installs a live CD or DVD image (ISO image) onto a USB storage device. The USB storage device can then boot the installed operating system on systems which support booting via USB. B<livecd-iso-to-disk> requires an ISO image and a USB storage device. The ISO image may even be the currently running live media image. If the operating system supports a persistent overlay to save system changes, a fresh overlay, or a copy of the currently running overlay may be included in the install. This enables one to easily prepare customized live media images for redistribution. (ISO images can be created with B<livecd-creator>.)
| |
| | |
| B<livecd-iso-to-disk> is not a destructive process; any data you currently have on your USB stick is preserved.
| |
| | |
| =head1 OPTIONS
| |
| | |
| =over 4
| |
| | |
| =item --help
| |
| | |
| Displays usage information and exits.
| |
| | |
| =item --format
| |
| | |
| Formats the USB stick and creates an MS-DOS partition table (or GPT partition table if --efi is passed).
| |
| | |
| =item --reset-mbr
| |
| | |
| Sets the Master Boot Record(MBR) of the USB storage device to the mbr.bin file from the image's syslinux directory.
| |
| | |
| =item --efi
| |
| | |
| Create a GPT partition table when --format is passed, and install an hybrid EFI/MBR bootloader on the disk. This is necessary for most Intel Macs.
| |
| | |
| =item --extra-kernel-args <args>
| |
| | |
| Specifies additional kernel arguments, <args>, that will be inserted into the syslinux and EFI boot configurations. Multiple arguments should be specified in one string, such as, --extra-kernel-args "arg1 arg2 ..."
| |
| | |
| =item --multi
| |
| | |
| Used when enabling multi image copies to avoid boot configuration of a particular image.
| |
| | |
| =item --livedir <dir>
| |
| | |
| Used with multi image copies to select the particular image to boot.
| |
| | |
| =item --compress (default option to use a compressed squash filesystem)
| |
| | |
| Installs image on a compressed squash filesystem
| |
| | |
| =item --skip-compress (default for when option --xo is specified)
| |
| | |
| Installs the operation system into a ext3 filesystem image file.
| |
| | |
| =item --xo
| |
| | |
| Used to prepare an image for the OLPC XO laptop and its compressed JFF2S filesystem. Do not use the following options with --xo: --overlay-size-mb <size>, home-size-mb <size>, --delete-home, --copy-home, --copy-overlay, --compress
| |
| | |
| =item --xo-no-home
| |
| | |
| Used together with the --xo option to prepare an image for an OLPC XO laptop with the home folder on an SD card instead of the internal NAND flash storage.
| |
| | |
| =item --noverify
| |
| | |
| Disables the image validation process which occurs before the image is installed. When this option is enabled the image is not verified before installation on the USB storage device.
| |
| | |
| =item --skipcopy
| |
| | |
| Skips the copy of the live image to the USB stick. (Used to repair disk configuration files or while testing the script to avoid repeated and length copy commands.)
| |
| | |
| =item --overlay-size-mb <size>
| |
| | |
| This option specifies the creation of a persistent overlay and sets its <size> in megabytes. The overlay is additional storage available to the live operating system if the operating system supports it. The USB storage device must have enough free space for the image and the overlay.
| |
| | |
| =item --copy-overlay
| |
| | |
| This option allows one to copy a persistent overlay from a running live image to the new installation. Changes already made in the running image will be propagated to the new installation. B<WARNING:> User sensitive information such as password cookies and activity histories will be copied to the new installation! Scrub this information before using this option.
| |
| | |
| =item --delete-home
| |
| | |
| Must be explicitly selected when options --home-size-mb <size> or --copy-home are selected and there is an existing persistent home directory on the image.
| |
| | |
| =item --home-size-mb <size>
| |
| | |
| Specifies creation of a persistent home directory and sets its size in megabytes. Note that --delete-home must also be selected to replace an existing persistent home with a new, empty one.
| |
| | |
| =item --copy-home
| |
| | |
| This option allows one to copy a persistent home folder from a running live image to the new installation. Changes already made in the running image home directory will be propagated to the new installation. B<WARNING:> User sensitive information such as password cookies and activity histories will be copied to the new installation! Scrub this information before using this option.
| |
| | |
| =item --force
| |
| | |
| This option allows one to bypass the user confirmation for deletion of an existing home directory on the target device, if one exists.
| |
| | |
| =item --crypted-home (default, if home-size-mb is specified)
| |
| | |
| Encrypts a persistent home directory.
| |
| | |
| =item --unencrypted-home
| |
| | |
| Disables the encryption of the persistent home directory.
