  Well, I had some CentOS 5.3 and 4.8 servers too. But, I mirror the directory
structure and loop mount an ISO image on the "os" dir on it :)

  When a new version is released I link copy the "old" structure to a new one
(cp -al 5.3 5.4), mount the new media under the "os" tree, and run rsync against
a mirror of the new structure. I do this because sometimes there are packages in
common betwen both versions and I didn't need to download it (or store it, as it is
only a hard link) again.

  When I think the new version is ok to run in my production servers I simply move
the upper link from one version to another, i.e. fom 5 -> 5.3  to 5 -> 5.4, the yum.conf
files are set to get from the "5" repo and not from "5.x" 

   Hope this helps
