Description Andrew Walrond 2015-02-24 15:17:57 UTC 
I used systemd-nspawn -xbD to boot a minimal systemd based container.

When I shut down the container with 'systemctl poweroff', systemd-nspawn fails to delete the ephemeral btrfs snapshot because the container's systemd has created a btrfs subvolume on the container's /var/lib/machines directory.

Maybe containerised systemd shouldn't create this subvolume?

A minor irritation solved by manually deleting the two subvolumes, but I thought I'd report it.
Comment 1 Lennart Poettering 2015-04-14 13:27:18 UTC 
This is fixed in git, where the btrfs subvolume removal is recursive.
Comment 2 Andrew Walrond 2015-04-14 13:46:36 UTC 
Good man.

Recursive btrfs subvolume removal? I know to my cost that this is non-trivial so I'll be checking git before I try it ;)
