I am using an nfs-mounted /var/cache/yum, combined with keepcache=1
in /etc/yum.conf, and compatible /etc/yum.repos.d/*+/etc/yum.conf's on
each machine, for exactly these reasons.

The effect is a "package-cache", being populated by diverging demands of
different machines.

Works quite well as long as you don't run several "yum update"'s
accessing this /var/cache/yum simultaneously, because yum seems to have
problems in locking /var/cache/yum.
