2391ddff77 cgroups: add support for systemd cgroup hierarchy
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.

6b3a4110cc runscript: fix stopping changed service issues
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.

4f19c2f512 Support cpu usage management for Linux
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}.

5615fa78d6 Drop restart_pre/restart_post
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.

8c82637e76 fix references to functions.sh
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.

8d63719418 Change the working directory for depend only
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.

9d0dce35c3 Let runscript enter the service dir before expand globs
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.

9fa54a8e80 Runscript: allow extra_commands to be run in chroots
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.

d8bbeb184f CGroups: create the openrc cgroup hierarchy

services it starts and all subsystems attached to it. If you need other

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.

df1f02ac84 Runscript: print deprecation warning for opts variable
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.
