Title:
  Difference between lxc autostart from init script and manual lxc-start
  call

Status in lxc package in Ubuntu:
  Incomplete

Bug description:
  According to
  https://answers.launchpad.net/ubuntu/+source/lxc/+question/255408,
  there seem to be a difference between `lxc start` and the autostart
  feature lxc.start.auto.

  On my Ubuntu 14.10, I have problem starting up containers manually,
  but autostarting the same containers works without problems. I cannot
  see a difference, the file /etc/init/lxc-instance.conf is very simple
  and doesn't set any important additional environment variables.

  The log output is as follows

      lxc-start: lxc_start.c: main: 341 Additional information can be obtained by setting the --logfile and --logpriority options.

  The interesting thing is that the rootfs is mounted into
  /usr/lib/x86_64-linux-gnu/lxc/ instead of /usr/lib/x86_64-linux-
  gnu/lxc/rootfs/ which doesn't seem to be the case when starting up the
  machine.
