This would be very hard to do. On post install you know the target state
of the system, but how are you supposed to guess what are you roll
backing to ?

IMHO if you want working rollback rpm or yum needs to intercept file
writes and snapshot their previous state (which still leaves other
operations like sending dbus signals for the packager to rollback
manually)
