I've always thought yum should have its own 'reproducible updates'
concept so you could  update a test machine, then tell all the others
to update to exactly that state even if some new things had been added
to the repositories - without having to make complete snapshots of
repositories containing stuff you don't even have installed just to
hold the state.  That is, that should have been a design goal for yum
since that is the way people should manage multiple machines - and yum
does sort-of know how to do that if you specify every package version
number.   But it really should just need a timestamp of the latest
thing in the repo at the time of the test/master update and  ignore
anything newer when you want it repeated.
