We make the first process pid 2 (intead of 1 as in base LINUX), so that only if
init needs to get spawned do we specifically create pid 1 and exec init,
otherwise, if an init is NOT needed (dependent node), the pid 2 process just
sleeps forever.  We don't have pid 2 exit because all the system daemons are its
children and we don't want them inherited by process 1.
