Public bug reported:
When using child subvolumes (e.g. /var/lib/docker/btrfs,
/var/snap/lxd/common/lxd/storage-pools/default), restoring a snapshot
involves moving these child subvolumes manually.
I suggest to add a command "btrfs subvolume restore SRC DST" with an option
"--include-children" with the following behavior:
1. In case DST already exists, it could be moved to DST.bak
2. btrfs subvolume snapshot SRC DST
3. For all children of DST.bak, move to SRC
