Perhaps, but I was sure there was a snapshot property too, because I 
remember discussion of being able to unset it in ordered to remove it 
from the snapshot (only) list.

But maybe that's all it was, discussion, it wasn't implemented, and I 
ended up conflating it with the read-only bit, which /can/ be set/unset 
that way.  Like I said I can't check as I don't have any subvolumes/
snapshots available to do a listing on and see, and the property manpage 
doesn't have a properties list to check on, it wants you to use the list 
option to get the list.
