Actually, that's the problem that Red Hat Satellite Server can solve.
You can approve packages for deployment.  Thus, when provisioning new
servers, they get updates from the approved list.  And servers are
grouped by class.  For the free version, one should investigate Project
SpaceWalk.  http://www.redhat.com/spacewalk/
