Features:
+* Document boot options such as forcefsck
+
+* beef up links between systemctl output and man pages. i.e. add a new unit
+ file setting that links to man and other sources of documentation, and hook
+ all systemd internal units accordingly.
+
* (attempt to) make Debianites happy:
- implement .d/ auto includes for unit files
- add syntax to reset ExecStart= lists (and similar)
