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

When running an installation from a CDROM drive, the drive tray should open at the end of the installation. This is not happening any more and the tray stays closed.

It works with RHEL-10.2-20251118.1 / systemd-257-16.el10 (built using lorax-templates-rhel-10.1-3.el10)
It doesn't work with RHEL-10.2-20260113.3 / systemd-257-21.el10 (built using lorax-templates-rhel-10.2-1.el10)

The problem can be fixed by re-creating the installation images with the packages from RHEL-10.2-20260113.3, but downgrading to older lorax-templates-rhel-10.1-3.el10 on the build system.

RHEL-126547 was the only change in lorax-templates-rhel-10.2-1.el10, the relevant change is:
https://gitlab.com/redhat/centos-stream/rpms/lorax-templates-rhel/-/commit/b4fa4064edb449b237dcb9e64ea1599ef8cb7873

Instead of an empty /etc/selinux/config file in the installation environment we now have:

[anaconda root@localhost /]# cat /etc/selinux/config
SELINUX=permissive
SELINUXTYPE=targeted
[anaconda root@localhost /]#

And indeed, if I remove the content of the file before rebooting the system, the drive tray opens during reboot:

[anaconda root@localhost /]# cat /etc/selinux/config
SELINUX=permissive
SELINUXTYPE=targeted
[anaconda root@localhost /]# echo "" > /etc/selinux/config
[anaconda root@localhost /]# cat /etc/selinux/config

[anaconda root@localhost /]#

Please provide the package NVR for which the bug is seen:

RHEL-10.2-20260113.3
systemd-257-21.el10
dracut-107-3.el10
anaconda-40.22.3.39-1.el10
lorax-40.5.13-1.el10
lorax-templates-rhel-10.2-1.el10

How reproducible is this bug?:

Always

Steps to reproduce

1. boot a KVM VM from DVD.iso/boot.iso
2. start watching events from the VM using virsh:

   virsh event --domain <name> --all --loop
   

1. finish the installation and reboot at the end of the installation

Expected results

The media tray opens at the end of the installation, virsh reports:

event 'rtc-change' for domain 'rhel-10-eject-old': 0
event 'tray-change' for domain 'rhel-10-eject-old' disk sata0-0-0: opened
event 'reboot' for domain 'rhel-10-eject-old'

Actual results

The media tray doesn't open at the end of the installation:

event 'rtc-change' for domain 'rhel-10-eject': 0
event 'reboot' for domain 'rhel-10-eject'

Additional info

When running the installation with rd.debug on the kernel command line, dracut shutdown scripts are not executed at all in case of RHEL-10.2-20260113.3. See the attached logs from log_20251118.1 and log_20260113.3
