Make netmount look up services for file systems

The tmpfiles "d" entry will create a full path and only the last dir in
the path will have its SELinux label set correctly. This patch will
restorecon the parents as well so that the selinux labels are correct.

eg, "d /run/libvirt/lxc", then "lxc" would have the correct SELinux
label but "libvirt" would not.

+
+    Add rc-sstat script
+    
+    The rc-sstat script is written to display status of s6 services and
+    run rc-status to display all services status.
+    
+    This currently only works on Linux.

+commit 0b435ddd834bd18254c4d3341acdebf0829921f5
+Author: Jakob Drexel <jake42@rommel.stw.uni-erlangen.de>
+Commit: William Hubbs <w.d.hubbs@gmail.com>
+
+    librc: Fix crash if the service name is the same as the including runlevel
+    
+    If a service has the same name as the runlevel it is in, openrc will
+    crash on changing to such runlevel. It goes in a recursive madness and
+    eventually gets a SEGV while in snprintf (don't know why).
+    
+    This fixes two errors:
+    1. ls_dir stats files not with full path -> stat always returns != 0
+    2. ls_dir adds files to list if stat failed
+    
+    This fixes #53.

+# Using S6 with OpenRC
+
+Beginning with OpenRC-0.16, we support using the s6 supervision suite
+from Skarmet Software in place of start-stop-daemon for monitoring
+daemons [1].
+
+## Setup
+
+Documenting s6 in detail is beyond the scope of this guide. It will
+document how to set up OpenRC services to communicate with s6.
+
+### Use Default start, stop and status functions
+
+If you write your own start, stop and status functions in your service
+script, none of this will work. You must allow OpenRC to use the default
+functions.
+
+### Dependencies
+
+All OpenRC service scripts that want their daemons monitored by s6
+should have the following line added to their dependencies to make sure
+the s6 scan directory is being monitored.
+
+need s6-svscan
+
+### Variable Settings
+
+The most important setting is the supervisor variable. At the top of
+your service script, you should set this variable as follows:
+
+supervisor=s6
+
+Several other variables affect s6 services. They are documented on the
+openrc-run man page, but I will list them here for convenience:
+
+s6_service_path - the path to the s6 service directory. The default is
+/var/svc.d/$RC_SVCNAME.
+
+s6_svwait_options_start - the options to pass to s6-svwait when starting
+the service. If this is not set, s6-svwait will not be called.
+
+s6_service_timeout_stop - the amount of time, in milliseconds, s6-svc
+should wait for a service to go down when stopping.
+
+This is very early support, so feel free to file bugs if you have
+issues.
