The systemd cgroup hierarchy support is being added so we can run
logind outside of systemd. This is needed because software that was
using consolekit is now migrating to logind.
We do not create this hierarchy, we just add services to it if it
exists.
sh/rc-cgroup.sh.in: new script to handle cgroup processing
sh/rc-cgroup.sh.in: do not use grep or cut (modification by William Hubbs)
sh/runscript.sh.in: use the cgroup script
If an init script or service was upgraded while it was running and the
settings for the pid file, command and process name were changed, it
would not be possible to stop the old service.
Runscript now saves the values it used to start the service and re-uses
them to stop the service.

This commit was modified by William Hubbs as follows:
- The paths in the cgroup fs were put into variables to ease
maintenance.
- Documentation was added to rc.conf.Linux.
- The services were added originally to openrc/svcname cgroups under the
controller cgroups, but this left an "openrc" cgroup which was unused.
Now they are added to individual cgroups with the name openrc_${RC_SVCNAME}.
By design, restart is hard coded to run stop followed by start along
with all of the pre/post functions associated with them. Restart doesn't
need its own pre/post functions since it is possible to make any
function in an init script behave differently for a restart command by
testing against the RC_CMD environment variable.
There were a couple of places where we were sourcing functions.sh in
@SYSCONFDIR@/init.d. This is only a backward compatibility symlink, so
it should not be used for openrc. The correct place to source this from
is @LIBEXECDIR@/sh.
We already have a special case for depend processing, so we should
change the working directory there only. This prevents us from forcing
all init scripts to be run in the init directory.
Enter the service directory, like gendeps.sh does, to make sure globs are
expanded in it rather than in /. That makes sure that globbing like "need *"
will end up in all files of the init.d directory.

The commands defined in the extra_commands variable do not depend on
whether the service is stopped or started, so it is valid to run them in
chroot environments.
Also, add a note to the runscript man page about the commands in
extra_commands being able to run whether or not the service is started.

The start-stop-daemon "--make-pidfile" option is now used by default when using
command_background, this requires a pidfile to be specified.
Document command_background option.

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.
