 Oracle Linux 9 for All in One ILMT Server

Has anyone tried using Oracle Linux with RHEL compatible kernel for the All in One ILMT install? 

Official documentation says not supported but the two operating systems are binary compatible. RHEL is not our standard image so significantly more work to stand up. Windows is an option but the microsoft tax is not ideal.

Thanks!

The setup script (setup-server-linux-x86_64.sh) would not work with Oracle Linux.
It is specifically looking for Red Hat release.
 
'/etc/redhat-release' / 'rpm -qf /etc/redhat-release' gives different outputs:
oraclelinux-release-9.4-1.0.6.el9.x86_64
vs
redhat-release-9.4-0.4.el9.x86_64


You would have to export a following vraible:
disable_platform_check=true
before executing setup script to get around of this OS check issue.
 
 
Furthermore, running Db2 on Oracle Linux is also not officially supported, though it may work.
 
At last, 
I still see this as a kind of custom scenario which doesn't necessarily meet all the requirements of the certified operating system.
Opening suppport tickets for any potential ILMT server malfunction would be questionable.
