[Yum] Include one .conf file in another?

[Hedemark, Magnus]

I was thinking about this and wonder if it might be best to have something
like /etc/xinetd.d/* where you have a number of services defined, each in
their own file, and by default most of them are disabled.  That way if a
sysadmin wants a machine to become a CAD workstation, he changes the "false"
to "true" in a file like /etc/yum.d/cadgroup.conf

Trying to think in terms of large scale deployments, and allowing dept.
sysadmins to add new configurations without having to touch the central
MIS-owned configuration in environments where you have centralized
deployment with some local department level support.
