Remember that this isn't quite so useful, because you can't make
read-only snapshots in that structure.

Generally, I'd recommend not having nested subvols at all, but to
put every subvol independently, and mount them into the places you
want them to be. That avoids a lot of the issues of nested subvols,
such as the ones you're trying to deal with here.
