Not sure about not mirroring multiple architectures or versions, I don't see how that is avoidable. But our repos in cobbler are defined only using variables.
Instead of
$ cobbler repo add --mirror=http://download.fedora.redhat.com/pub/fedora/linux/updates/12/ --name=f12-i386-updates $ cobbler repo add --mirror=http://download.fedora.redhat.com/pub/fedora/linux/releases/12/Everything/i3... --name=f12-i386-everything
use variables instead
We use an mrepo server to host/create/manage our internal repos. (It generates the same url paths as the public repos, but with our internal hostname)
All our repos have essentially the same urls for updates, base, centosplus, extras
