Any system using cgroups was being detected as an LXC system. This was
triggering on OpenVZ under RHEL6 as well as the "automated per tty task
groups" as discussed on the LKML.
All LXC users should now switch to the new rc_sys variable introduced in
the previous patch.

- Fixes bugs #347583, #349389, both of which were triggered by cgroups
being detected as the LXC subsystem type.
- Makes it much easier to select "prefix" type.
- "rc -S" will now print a warning if you have not configured rc_sys in
/etc/rc.conf
- All other semantics of rc_sys are unchanged in this patch.

Under normal conditions, runscript creates one child and waits for its
termination, which is signaled by a pipe write from the SIGCHLD
sighandler.
When running killprocs however more than one SIGHCLD signal is generated, at
least on all of my amd64 boxes running on real hardware and in vmware.
When the first SIGCHLD occurs svc_exec leaves the loop and closes the pipe.
Subsequent SIGCHLDs during the close can lead to a race condition and create an
EBADF error in the pipe write (pipe is closed but the file handle is still !=
-1).
We avoid this by blocking SIGHCHLD during the pipe close.
Gentoo has always used the sytle:
* moo ... [ ok ]
Latest openrc now does:
* moo... [ok]
Realistically, 4 spaces out of 80 on reduced terminals doesn't make any
sort of realistic difference and it's been just fine for the last 10
years, so keep the default behavior.
the mtime of a file. It saves the shutdown time to this file also.
This is handy for systems without a working RTC chip.
Based on an idea by Michael A. Smith <michael@smith-li.com>.
Fixes Gentoo #272073.
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.
