Description Christophe Besson 2023-06-23 11:19:41 UTC

Description of problem:
Our customer was using Lorax in the past, and kept it for RHEL 8, despite being deprecated in favor of osbuild-composer.
But the latest backend does not provide a "live-iso" image type as the former backend did.

RHEL 9 still provide lorax-lmc-novirt, without the KS templates with (many) tricks related to a live desktop session (which were stored in /usr/share/doc/lorax/rhel-livemedia.ks).
Using the RHEL 8 one allows me to create a RHEL 9 live image, but some hacks didn't work.

One of the major customer expectations is to have the squashfs (containing the standard rootfs customized by the blueprint != anaconda installer) loaded into RAM (allowing the USB to be unplugged). Not sure it should be the default (as it can be enabled with rd.live.ram=1).

Please see these upstream issues that are closely related:
 * Live images for PXE boot output format #472 - https://github.com/osbuild/osbuild/issues/472
 * https://github.com/osbuild/osbuild/pull/430

Version-Release number of selected component (if applicable):
osbuild-composer-76-2.el9_2.2.x86_64

Doable with lorax-lmc-novirt and livemedia.ks

FYI there is still an example kickstart, it was renamed to /usr/share/doc/lorax/livemedia.ks, and it does work on RHEL 9.2 just fine.
