Because you can't guarantee that rpm is the only thing accessing the
FS. Indeed some things, like logfiles, are pretty much guaranteed to be
changing the FS. So unless you had complete FS transactions that you
could rollback, and made sure all the things rpm did was within a
transaction, rolling the entire FS back is worse than the problem IMO.
