The linux kernel documentation suggests mounting a separate cgroup
hierarchy for each subsystem you want to control/monitor. This changes
the cgroups mounting code to do this.
Openrc will create a cgroup hierarchy called openrc which will have all
services it starts and all subsystems attached to it. If you need other
groups/hierarchies, please use libcgroup.
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.
mounting various bits in /dev and /sys.
init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems)
To make development of this easier we now return an empty RC_STRINGLIST
instead of a NULL for empty things.
If you don't have a udev init script installed, don't reboot your box OR
roll back to an older OpenRC version.
