Title:
  [16.04, lxc] Failed to reset devices.list on ...

Status in systemd package in Ubuntu:
  Confirmed

Bug description:
  This seems to be identical to Bug #1413193 which affected 15.04 and
  was marked Fix Released.

  On a 16.04 host with a 16.04 container:

  $ lxc-create -t download -n vpn01 -- -d ubuntu -r xenial -a amd64
  $ lxc-start -n vpn02 -d

  the container syslog shows repeated instances of "Failed to reset
  devices.list on ..." and continues generating such messages:

  $ grep devices.list .local/share/lxc/vpn01/rootfs/var/log/syslog
