The question is what the rpm versions would be in the rollback release -
at the moment they are tied to the code version in cvs, so you can't
produce rpms with different versions from the same code (and if you
could it would make it a lot harder to figure out which source code is
in which rpm).
Also in general I don't see how a simple upgrade to the previous
version is going to work if there has been a configuration change. For
example, we just caught a configuration bug on the PPS which results in
bad publication in the information system. Fixing the bug should be
fairly simple, but reinstalling the old rpms wouldn't help because the
new configuration has wiped out the old one. And updating the
configuration to undo the change would be pointless since, at least in
this case, it's easier to just fix the bug.
