Bug#803013: systemd should not destroy application created cgroups

Could do; or do on a throw-away partition; either way it takes hours,
not minutes. I presume you have an "unstable" machine handy. Then you
can test in seconds (as root):

  # Set things up
  mkdir /sys/fs/cgroup/cpu/mytest
  echo $$ > /sys/fs/cgroup/cpu/mytest/tasks
  # Check it is there
  grep . /sys/fs/cgroup/cpu/mytest/tasks
  # Do the systemd thing
  systemctl daemon-reload
  systemctl start anacron
  # See it gone
  grep . /sys/fs/cgroup/cpu/mytest/tasks

Please let me know...

Cheers, Paul
