cgit -> git I added some info on the systemd and Upstart pages. I added some links to other multiserver OSs. some tweaks to the systemd and upstart wiki pages. more info added to the genode OS page. I added a GNU Shepherd page.

+Systemd uses Linux kernel specific mechanisms, which are not readily available
+on gnumach or the GNU/Hurd. Porting systemd to work on the Hurd is a
+daunting task. A better option is to use a portable init system, like the
