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.
When a CGroup is created, we need to copy cpuset.cpus and cpuset.mems
from the new group's parent into the new group before we can attach any
processes to it.
symbolic links should not be followed in an attempt to work out the name
of the service we are running. Also, @sysconfdir@/conf.d should be tried
as a backup directory for configuration files.
I would like to thank Robin Johnson for his input on this change.

Openrc uses the extra_commands and extra_started_commands variables to
list extra commands for services. Also, it supports the opts variable
which is used to assist migration from baselayout-1.
I am adding this warning to encourage switching from opts to
extra_commands/extra_started_commands.
I would like to remove support for opts eventually.
* status on a stopped service now has a return code of 3 (was 1)
* starting an already started service now has a return code of 0 (was 1)
* stopping an already stopped service now has a return code of 0 (was 1)
runscript.sh needs to abort if the . command used to load
conf.d files and the service script does not execute successfully.
I would like to thank Mike Frysinger for his input wrt style on this
patch.
OpenRC version is now stored as plaintext in /libexec/rc/version
Plugins (cursplash, splashutils) will have to be re-compiled to pickup
the new directories. State data needs to be moved from /lib/rc/init.d
to /libexec/rc/init.d as well.
