I'm confused by the use of parent in this context. Do we have more than one kind of "parent"? Example below shows four subvolumes (not snapshots), and the last one is a snapshot of the first. # btrfs sub list -p /mnt ID 257 gen 1414 parent 5 top level 5 path root ID 258 gen 1351 parent 5 top level 5 path home ID 259 gen 139 parent 5 top level 5 path boot ID 262 gen 1407 parent 257 top level 257 path root/var/lib/machines ID 264 gen 1413 parent 5 top level 5 path rootsnap If this "parent" has anything to do with snapshots, I'd expect the last line to read: ID 264 gen 1413 parent 257 top level 5 path rootsnap And for that matter I don't know what I expect for the fourth line: ID 262 gen 1407 parent ? top level 257 path root/var/lib/machines It has no parent, none of the non-snapshot subvolumes do. I don't think it's OK to repurpose "parent" if it has two contextual meanings.
