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. -- Any sufficiently advanced technology is indistinguishable from magic. -Arthur C. Clarke
