I don't think that the srpms packages make a distinction whether they belong to AS or ES. AFAIK theres only two or thee packages in AS that are not present in ES (clustering, HA) I think that AS and ES distinction applies mostly to RedHat's support level and hardware limitations. > Is the SRPMS for RHEL built on a RHEL AS > build computer to generate CEntos RPMS? No idea. Would that make a difference? Andy
