Public bug reported:

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.
