strace log

Hi

Running `systemd-nspawn -D / -xb` produces the following error for me:

  david@david-t2 ~/dev/systemd $ sudo ./systemd-nspawn -D / -xb
  Failed to create snapshot /.#a726c057b3fe24c6 from /: No such file or directory

I tracked this down to btrfs_subvol_snapshot(), and subvol_snapshot_children() in particular. If called with BTRFS_SNAPSHOT_RECURSIVE, it fails in the recursion step.

My root system consists of the root snapshot at '/', and a btrfs snapshot at '/var/lib/machines'. The strace output is attached.

Thanks
David
