58e04035ed Cgroups: do not update mtab when mounting control groups
This is based on a patch submitted by the reporter; however, there was
another mount command which needed -n as well so it was added to the
patch.

de5cee2c21 cgroups: make sure /sys/fs/cgroup is a mount point
We need to make sure this directory is a mount point before we add the
control groups.

ce4c9b5397 Cgroups: create openrc control group
This creates the "openrc" control group with no subsystems attached. The
next step will be to add everything openrc starts to this group.

cd52fecc4e cgroups: turn on groups by default
The control groups we create are the ones recommended by the linux
kernel, so this should be on most of the time if cgroups are enabled in
the kernel.

3e2001f6a2 add rc_cgroup option to allow disabling of cgroup default setup
Currently, cgroups are still in development, so we are not setting them
up by default. However, this default will be changed in the future.

461c69acdb cgroups: mount cgroups suggested by the kernel documentation
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.

d8bbeb184f CGroups: create the openrc cgroup hierarchy
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.

0510c473d4 CGroups: /sys/fs/cgroups should be a tmpfs
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.

b4104957b1 We should use -feature instead of nofeature.
This matches the ifconfig and Gentoo USE flag syntax and is hopefully
easier to read.
Fixes #178.

d6da8e8c48 sysinit is now a real runlevel that handles things like udev, dmesg and
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.
