Let me ask you how will snapshotting and restoration work with nested sub volumes?
They have to be moved into the new position following the rollback.
This could be done either with a literal 'mv' or you could just
snapshot the old location to new location, then delete the snapshot
from the old location.
Let's say I snapshot my root subvolume which contains a subvolume
which contains my VM images.
The snapshot will stop at the nested subvolume boundary, i.e. it will
not be included.
What will happen to this volume when I restore my root snapshot?
The rolled back root subvolume will have an empty directory matching
the name of the nested subvolume.
