Sure, the DVD includes a yum repository on it, or you can sxtract the
iso images to make a yum repository of your own. Running an internal
yum mirror in such a fasion is an easy way to cut down on bandwidth
use depending on how many machines you have. From here you can even
rsync from available mirrors to maintain updates between versions.
