At the end of the day, if the OS doesn't give you atomic multi-file transactions, and your %pre/%post scripts aren't also written perfectly atomically, I would say that it _is_ impossible.
In any case, are there reasons to believe that behaviour in rpm has improved (in F11) in the face of a powerloss in the middle of a transaction? If we start doing OS upgrades and removing power at random points, what chance does rpm of recover/resume?
It is an admittedly hard question.
