Whats an even cooler solution is if you add a versioning layer to the filesystem, and make files be markable as versioned. Add some sort of labeling support, and you got something really cool. Actually that is my dirty little rollback secret. I didn't just use rpm's transactional rollback, I combined it with a tool I wrote called RCSTool, and an upgrade/rollback script that did a few other things. Essentially, rpms transactional rollback was just part of my rollback story.
