I'm running Centos on 12 machines.

Colleague runs Redhat Enterprise Linux and while studying his system, I see some gibberish/complication about his system being a "Client" install, not a "Server" install. Apparently, RH provides completely different disk sets for Server and Client installs. I've gone to the RH website and read about the difference between Client and Server, but I still don't understand why they make 2 different disks. In the "old days" of RH, there would be 1 set of disks, and when the install began, you would choose "server" or "workstation" as a way of choosing a default set of packages, and then you could freely pick and choose additional things. You could install gnome on a server, or an http server on a client.

Centos seems to follow the good old RH packaging approach.

This RHEL Client/Server thing actually causes some wrinkles if you try to transition a running system from RH to Centos, because the repository names are different. RH will have a version name like "5client" whereas Centos will just have 5.

I understand this Centos list is not quite the right place to ask "why does RedHat do that?", but I bet some of you will know.

What I really want to ask here is: what is the relationship between the several RHEL install types and the Centos disks? Does Centos collect up all the SRPM/RPM packages from both RHEL Client and Server?
