* properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
Features:
+
+* document the exit codes when services fail before they are exec()ed
+
* use the rtc which has: /sys/class/rtc/*/hctosys == "1" as the system RTC
* rework namespace support, don't use pivot_root, and mount things after creating the namespace, not before
