Hi James,

to verify that this is a dup of bug 1413927, could you please

1. update your host to get lxcfs 0.4 :)

2. cat /proc/self/cgroup, get your name=systemd cgroup

3. under /sys/fs/cgroup/systemd/$(yourcgroup) chown your cgroup (i.e.
/user.slice/user-1000.slice/session-c2.scope) and the tasks file under
that to your uid?

4. re-try starting the container

Title:
  lxc unprivileged containers broken

Status in lxc package in Ubuntu:
  Incomplete

Bug description:
  Seems to be due to 1.1.0~rc1-0ubuntu1 landing?

  $ lxc-start -n trusty --logfile /tmp/lxc.log --logpriority debug
  lxc-start: lxc_start.c: main: 345 The container failed to start.
  lxc-start: lxc_start.c: main: 347 To get more details, run the container in foreground mode.
  lxc-start: lxc_start.c: main: 349 Additional information can be obtained by setting the --logfile and --logpriority options.

  lxc.log attached.

  On a related note, it seems that the dep8 tests I originally wrote for
  lxc [1] have been replaced to call lxc's own test suite. However,
  whereas these new tests are somehow passing in jenkins [2], I belied
  the crude tests in [1] would have caught this issue as they actually
  call the command-line tools users run.

  Could we maybe bring back [1] and run both sets of tests to avoid such
  a regression in future?
