The above link shows how it is done. Doesn't work well in all instances 
since scriplets in rpm might not be undone easily. In fact, this 
"feature" has been dropped in the rpm in rawhide. If you want proper 
undo support, it should be a filesystem level feature. Something like 
btrfs in the (near?) future.
