Surely you don't have to maintain the original .rpm file to use a delta-rpm. The original .rpm could be re-constructed on the fly from the packages that it installed.

So yes, deltarpm magically takes both the rpmdb and the delta file and produces a full (non-delta, perhaps .patch) rpm out of it. And that takes a whee while.
