IIUC with BtrFS while it is possible to easily undelete a file or
ordinary directory if a snapshot of the containing subvol exists, it
seems that it's not elementary to undelete a subvol itself, because
all subvols are under the root-level subvol (id 0 or 5, see my other
q) but even snapshotting the root subvol will not snapshot any subvols
under it.
So is there any way to undo a subvol delete?
[If no, then ordinary users should probably prefer regular directories
to subvols.]
One solution is using snapper instead of using btrfs directly.
Snapper can automatically take a snapshot just before
taking/deleting snapshots. So, if you delete a snapshot
by mistake, it's still alive.
