No matter how hard you try, there will always be a small period in
time where mirrors are out of sync. And this especially holds for the
synchronization between the main Fedora repo and third party repos.

So there should be a mechanism developed to make yum aware of the fact
that one repo (or mirror) it uses is behind others - because that can
lead to (virtual) dependency problems which probably should be
reported to the end user in a different way than intra-repo dependency
problems.
