It'd be nice to have comps-enabled repodata on the install media (at least the
DVD, perhaps also CD's) so one could use it or the mounted ISO as the "base"
component in yum as-is, instead of having to stick with an online one or to
generate the repodata locally.
Having it on the DVD sounds doable. The binary CDs are chock full of wonderful
goodies, leaving no room for repodata just now.
