The kernel documentation states that a cgroup file system should not be mounted here, but a tmpfs. This also means that we should not create a group for each process, but we should allow the user to specify which group a process should be assigned to. The rc_cgroup variable will be used for this purpose. For more information, see /usr/src/linux/Documentation/cgroups/cgroups.txt.
