or compile them yourself.  if you really care about them,
you probably want to anyway.  significant updates don't happen _that_
frequently, though this is obviously less viable for a one-man-cluster
than a center with several admins.

I think fedora could be made to work OK in a cluster, despite its update
rate.  it would do so easier on a cluster which had lots of short jobs.
(our clusters frequently have multi-week jobs, so we tend to update system
stuff less frequently, and centos/rh and derived systems like xc work well.)

I think centos+site-updates is a good model.  if nothing else, users may not
want updates/disruptions as fast as fedora's comes.
