This is a clone of RHEL-83519 for RHEL-9. The difference is that lmc on RHEL-9 finishes, however there are D-Bus related errors when the installer is starting. With the change below, the problem is resolved.

What were you trying to do that didn't work?

# livemedia-creator --make-disk --iso /var/lib/libvirt/images/RHEL-10.0-20250313.2-x86_64-boot.iso --ks minimal.ks --nomacboot

The process hangs. After connecting to the VM there are dbus-broker-launch related errors. We saw such a problem in the past, it was caused by missing the exec permissions in the CPIO archive attached to the original installation initrd. (See RHEL-11128). And indeed, changing the permissions fixes the problem here as well. Tested with the following change:

diff --git a/installer.py b/installer.py
index bf1d8aa..b6cda01 100644
