Rebecca Cran 3affea8f99 To restart, sysinstall calls execl. Since it will create a new process, we
can't check to see if sysinstall is running as init just by checking if the
PID is 0. Introduce a new option that sets the RunningAsInit flag, and update
the code to check RunningAsInit intstead of getpid().
