Description of problem:
Upon provisioning a machine with beaker, the yum repositories aren't descriptively named: they are all of the form "beaker-distro([0-9]+)"

# yum repolist

beaker-tasks            beaker-tasks             enabled: 7,229
repolist: 9,679

Is it possible to make them a bit more descriptive? (yum uses them in various places in the textual UI, and right now I never know quite what I'm getting)

e.g. (on this host), something like the following would be nice:
  beaker-RHEL-5-Server-U5-ia64-Cluster
  beaker-RHEL-5-Server-U5-ia64-ClusterStorage
  beaker-RHEL-5-Server-U5-ia64-Server
  beaker-RHEL-5-Server-U5-ia64-VT
  beaker-RHEL-5-Server-U5-basearch-Supplementary
(taken by mangling up the baseurl by hand)

(I'm not sure what yum's repo naming restrictions are, but I'm guessing alphanumeric-plus-dashes and not too long would do it)
