I have, expect to see FC4 and 4ES/CentOS 4 support in the upcoming Atomic-PSA rpm. Lots of neat features in FC4, php 5, mysql 4.1 and Xen virtual server support.
It currently lives in my [atomic-testing] yum channel. I am very much in need of alpha testers for atomic-psa, especially people running FC4 and 4ES/CentOS 4.
