Well, it's one of those things where you have two imperatives and you 
can't possibly satisfy both: be space efficient but also ensure that any 
installation done from the images will be complete and sensible. I think 
pungi makes the choice to prioritize the latter. Any kind of 'space 
efficiency' code is going to come with a non-zero danger of resulting in 
dependency problems or odd dependency resolutions, I guess.

I recommend it - it's not hard to probe out why these things happen 
(usually), and it can be quite fun. BTW, QA does have a test which looks 
for non-explicit conflicts or incomplete dependencies on the images and 
we hit those every so often, so we're pretty used to poking through 
things like this. It often tracks out to something which was a packaging 
problem in the first place and needed to be fixed. If you wind up 
getting stuck, poke dgilmore in #fedora-releng, as he should have the 
logs of the compose to look through which can help identifying some of 
the issues.
