this is delta vs full image ... 
there is no concept of unapplying deltas in system-image, they are just
accumulatively going forward ... 
so a switch works (because it reinstalls a full image without touching
userdata) but reverting a delta doesnt because the code for that only
knows how to unpack the delta tarball on top of an existing image.
