There is a bug (which is fixed in newer versions) in lxc in that it does not ignore cgroups which are not used by the container. So in your particular case, if you're not using the co-mounted controllers, then indeed fixing the lxc bug should work for you as well.
Nevertheless some people will want to run containers using those controllers, so cgroup-lite (and cgroupfs-mount) will need to be fixed. But that's not your problem :) I understand if you want to leave it at this - I'll just need to improve my awk skills :) I just wanted to ask to avoid duplication of effort.

This is because systemd now comounts multiple controllers on a single hierarchy, which prevents mounting them individually inside the container. =========== SRU Justification ================ Impact: nested containers fail to start Reproduce: create a root owned container; install lxc and cgroup-lite; create a container, and try to start it. Starting will fail if cgroup-lite is running in the first level container without this patch. Regression potential: should be low, it's possible that the regexp is simply wrong for some cases. =============================================== To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgroup-lite/+bug/1668724/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
