Thanks for all your help previously, Martin.

Title:
  Intermittent lxc failures on wily, juju-template-restart.service race
  condition

Status in juju-core:
  Invalid
Status in systemd package in Ubuntu:
  Invalid

Bug description:
  Frequently, when creating an lxc container on wily (either through
  --to lxc:#, or using the local provider on wily), the template never
  stops and errors out here:

  [ 2300.885573] cloud-init[2758]: Cloud-init v. 0.7.7 running 'modules:final' at Sun, 25 Oct 2015 00:28:57 +0000. Up 182 seconds.

  [FAILED] Failed to start Update UTMP about System Runlevel Changes.
  See 'systemctl status systemd-update-utmp-runlevel.service' for details.

  Attaching to the container and running the above command yields:

  I have seen this on ec2 and in canonistack.  The canonistack machine
  is available for further debugging.  Ping me for access.

  Reproducer from a clean wily cloud image
  ----------------------------------------
  sudo apt install -y juju-local
  juju init
  sed -i '/default-series/ { s/# //; s/trusty/wily/ }' .juju/environments.yaml
  juju bootstrap
  juju deploy wily/ubuntu

  iterate with
  juju destroy-service ubuntu
  juju destroy-machine 1
  sudo lxc-destroy -n juju-wily-lxc-template
  → then you can re-run "deploy".

  At some point this should hang on the creation of juju-wily-lxc-template, i. e. that container never stops.
  (Note: Martin Pitt could not reproduce this yet with these steps)
