Right now, snapshots of subvolumes do not contain the contents of contained subvolumes. Hmmm, that sounds horrid. Subvolume A File 1 File 2 Subvolume B File 3 File 4 If I snapshot subvolume A, the resulting snapshot does not contain File 3 and File 4. Subvolume B is a regular folder in the snapshot of Subvolume A. So if every directory were a subvolume by default, this limitation would need to be resolved or snapshotting would become useless. I'm sure there's a more coherent explanation why this isn't desired. > That way the snapshot can share inodes with is source. Snapshots already share inode numbers.
