Note the following images were tested at some point :

Image	Status	Description
AWS1	Highly deprecated (please stop using this !)	legacy AWS AMI , rh6 like , no systemd or wlm !
RH/Centos 7	Deprecated	No longer supported , yum update is so slow.....
RH/Centos 8	Deprecated (*)	works fine but you need a version with os updates/support !
RH/Centos stream 9	ok but slightly tested	systemd support and cgroup logic for AL2023 should handle all cases but not all versions tested
AWS2	OK	Highly tested but you may want to migrate before support end, see https://aws.amazon.com/amazon-linux-2/faqs/
AL2023	OK	newer and latest, cgroup automatically downgraded to v1 at the moment
