ok, so you decide when you want to upgrade your prod servers.
you make sure you have a local copy of 5.4 available somewhere and  
change the symlink so yum has access to the rpms.

another question:
do 5.4 rpms at some point end up in the 5.3 update repo?
(if this is the case I don't have to do anything but wait for them to  
show up)
or do I always have to rsync 5.4 over and arrange my files so that yum  
finds them in the "5" directory
(and not "5.4")
