I fully agree with two expections:

  1. "options GDB" should not be included by default because it opens a nasty
     security hole via firewire and if someone has easy access to the serial
     ports.

  2. Unattended should be compiled in.  Thus the box panics and gives a traceback
     but will reboot after 15 seconds.
