That could get tricky. We only support reverting to the last snapshot if we
reuse the same volume. Otherwise, we can create volume from snapshot, but I
don't think it's often that the first thing a user does is create a snapshot on
initial creation of a boot image. If it was created from image cache, and the
backend creates those cached volume by using a snapshot, then that might be an

But these are a lot of ifs, so that seems like it would make the logic for this
much more complicated.

Maybe a phase II optimization we can look into?
