Comment 10 for bug 1455358

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.
