efa9ba485d init.d/sysfs.in: fix reference to RC_LIBEXECDIR
The sysfs init script referred to @LIBEXECDIR@ before this change, but
it is better to refer to RC_LIBEXECDIR so that we get rid of a sed
substitution.

In hybrid mode, we should not try to mount cgroup2 if it is not
available in the kernel.

5f5b1f7cbe init.d/sysfs.in: efivarfs tweaks
Since we check for /sys/firmware/efi/efivars, we do not need to check
for /sys/firmware/efi

Since Failing to mount efivarfs is not critical, we silence the error
message from mount.

6a79aef015 init.d/sysfs: Do not load efivarfs module
My understanding is that the kernel can autoload this module. If it
doesn't, the module should be built in or loaded from an initramfs.

This fixes https://github.com/openrc/openrc/pulls/112.

6a0c033a64 init.d/sysfs: fix efivarfs handling
Separate loading the module, if it isn't built in or loaded, from
mounting the file system.

This also makes sure the warning about configuring the module in
/etc/conf.d/modules or building it in is displayed only if it is loaded
successfully.

73cdf10f1f Deprecate automatic loading of modules
In the hwclock, procfs and sysfs service scripts, we automatically
attempt to load the kernel modules we need before we take any action. We
shouldn't do this, because there are systems which do not use kernel
modules and do not have the kmod package installed.

With this change, we continue to load the modules ourselves, but we warn
the admin that they need to be added to /etc/conf.d/modules or built
into the kernel.

In the future, this automatic loading will be dropped.

000503fad7 Convert OpenRC to a centralized copyright/license structure
In the past, OpenRC was a hybrid of a centralized and file-scope
license/copyright structure.

I followed the instructions from the Software Freedom Law Center [1] to
convert to a Centralized structure where possible, for easier future
maintenance.

4f4f00d612 cgroups: fix cgroup subsystem mounting
Originally, we aborted all of the cgroup setup if /sys/fs/cgroup/openrc
was already mounted. This  caused an issue in lxc containers, so we
should always allow the subsystems to be mounted.

3470eda3f5 Rename runscript to openrc-run
This was requested by Debian, because the minicom software, which is
available on Debian and other distros, has a binary named runscript. We
are keeping a backward compatibility symlink for now, but this allows
Debian or any other distro to safely remove the symlink.

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.
