I forgot one more big change, kojipkgs (the web server our builders use to
get the packages off the nfs share) now has a squid server on it.  Instead
of pulling from the nfs share for every build, it pulls from squid now
instead.  We're seeing a 98% hit rate. (So only 2% of the requests for our
builds now actually hit our NFS share)
