I've tried to run the test on my machine where cgroups are allready mounted to /sys/fs/cgroup (which seems to be the case for modern distributions). In such situation the mount in the test fails with EBUSY. I looks like the root hierarchy can be mounted only once. Now we cannot unmout the /sys/fs/cgroup as this one is used by the system. But it looks like we can mount each of the controllers, i.e. for each controller: mkdir /path/type mount -t cgroup -o type type /path/type So the options are either to use the /sys/fs/cgroup directory or mount each controller one by one.
