--a Wait for 2 dhcp acks, then disable the pxe server after a delay.
- First ack is for pxe boot, 2nd ack is for os boot. Sometimes
- on debian, there is a 3rd one shortly after the 2nd. I can't remember
- exactly why this caused a problem, but I'm hoping the sleep
- will take care of it.
--w Initially setup pxe, then wait like -a.
