Documentation
- Livemedia Creator: http://weldr.io/lorax/livemedia-creator.html
- Kickstart: https://github.com/rhinstaller/pykickstart/blob/master/docs/kickstart-docs.rst
Setup Environment
Cloud Base/Vagrant
If using the cloud base or vagrant images, install the needed kernel modules:
# dnf install kernel-modules-$(uname -r)
Install Mock
You should always do all work in mock, this will allow you to ensure that the compose environment matches the target environment.
# dnf install mock # usermod -a -G mock <user>
Setup Build Environment
To setup a Fedora 39 x86_64 environment use mock to setup and install tools.
Init Environment
$ mock -r fedora-39-x86_64 --init $ mock -r fedora-39-x86_64 --install lorax-lmc-novirt vim-minimal pykickstart livecd-tools
Get kickstarts
The official Fedora kickstarts are stored in a git repository. The 'master' branch is for Rawhide; there are branches for each release as well. You can use a kickstart from this repository (on the correct branch for whatever release you want your live image to be) as a base. You could also take a fully flattened kickstart from a recent official live image compose task as a base.
If you wanted a different arch or release you would use the correct mock configuration file.
SELinux
If your system is using SELinux, it needs to be set to Permissive mode while running lorax.
$ sudo setenforce 0
Running a Compose
Go into your prepared environment to do a compose.
$ mock -r fedora-39-x86_64 --shell --enable-network --isolation=simple <mock-chroot> sh-5.2#
If you need to copy files into mock then you can do that with
$ mock -r fedora-39-x86_64 --copyin filename /builddir
Copying to builddir puts the file in the working dir of the mock environment.
Flatten a Kickstart
The official Fedora spins are composed from templates. Flattening fully resolves the templates to a valid kickstart which can be fed to livemedia-creator. After copying a base kickstart into the mock environment, you can flatten it with e.g.:
<mock-chroot> sh-5.2# ksflatten --config fedora-live-soas.ks -o flat-fedora-live-soas.ks
Create the Live Image
Run livemedia-creator with the flattened kickstart and relevant options. This creates a Sugar on a Stick live iso that also has EFI/Mac booting support.
<mock-chroot> sh-5.2# livemedia-creator --ks flat-fedora-live-soas.ks --no-virt --resultdir /var/lmc --project Fedora-soas-Live --make-iso --volid Fedora-SoaS-39 --iso-only --iso-name Fedora-SoaS-39-x86_64.iso --releasever 39 --macboot
Example Output
<mock-chroot> sh-5.2# livemedia-creator --ks /flat-fedora-live-soas.ks --no-virt --resultdir /var/lmc --project Fedora-soas-Live --make-iso --volid Fedora-Soas-39 --iso-only --iso-name Fedora-Soas-39-x86_64.iso --releasever 39 --macboot

2023-11-22 17:17:27,071: Logs are in /builddir
2023-11-22 17:17:27,071: Results are in /var/lmc
Compose Results
The resulting images will be located in the mock chroot. Copy them somewhere outside of the mock-chroot.
$ cp /var/lib/mock/fedora-39-x86_64/root/var/lmc/*.iso $HOME
Note: The location will be different based on your mock configuration.
Cleanup
We can now safely clean up the build environment and set SELinux back to enforcing.
$ mock -r fedora-39-x86_64 --clean $ sudo setenforce 1
