Handle lxc-start/lxc-wait/lxc-attach race better

[Christopher Townsend]

In the 1.0.3 release, I worked around the lxc-start/lxc-wait/lxc-attach race using a 'sleep 0.5'. This doesn't guarantee the race will be avoided, so a better solution is needed.

We've finally figured out what is causing this. See bug #1452451 for more details.

The proper workaround is to use "lxc.auto.mount = proc:mixed" in the LXC config.

I'll be making the proper changes in the dev branch to use the proper workaround instead of the hacky sleep.

This bug was fixed in the package unity8-lxc - 1.0.4+15.10.20150609-0ubuntu1

---------------
unity8-lxc (1.0.4+15.10.20150609-0ubuntu1) wily; urgency=medium

  [ Chris Townsend ]
  * Bump version to 1.0.4.
  * Automount /proc to avoid a race when attaching to a container to run
    a command. Also remove the ugly sleep workaround. (LP: #1428848)
  * Cache a copy of upstart-sysv when downloading the Unity 8 Desktop
    Next ISO image. This will keep the ISO and the upstart-sysv package
    in sync. (LP: #1458236)
  * Catch the exception when distro-info-data is outdated during dev
    release transitions. Use the current stable release instead when the
    dev release has not been updated. (LP: #1448521)
  * Terminate the session instead of killing the user when logging out
    of the Unity 8 LXC session. This is much less aggressive and keeps
    ssh sessions alive. (LP: #1456604)
  * Use upstart-sysv in the Unity8 container instead of systemd. This
    fixes a slew of issues when using systemd in the container. (LP:
    #1437900)
