Needless to say, if there was a way to do safe FS-level RPM rollbacks,
lots and lots of people would be immensely pleased with that. :)

Of course, that is still rife with plenty of ways it can go horribly
wrong. E.g. what happens when a %post restarts a process, and then we
roll back the fs? Tricky stuff.
