Closing as Invalid as there's no good way around this issue in general. The kernel will let you mount controllers that were already mounted but will complain if options don't perfectly match. Those options may differ for a number of reason and making lxcfs match those from systemd just means, this will show up on non-systemd systems.
Similarly, you can usually expect to see this message whenever starting a container due to different init systems or even different versions of init systems using slightly different mount options. This doesn't prevent the mount and in most cases, really just causes one line in a log file. ** Changed in: lxcfs (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455358 Title: cgroup: new mount options do not match the existing superblock, will be ignored To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxcfs/+bug/1455358/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
