Fedora only keeps the latest updates in the updates repository, so, in 
Fedora's case, createrepo just sets --oldpackagedirs to the release path 
and the path of the previously available updates.

We could see about adding a new flag to createrepo; something like 
--deltanewestonly, which would only create deltarpms against the newest 
version of a package available in the repository.
