-TYPE is one of arch, plain, fai.
-HOST is a hostname known to the dhcp server, or default for all, or none to disable

--r         Don't redeploy fai config.
--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.
+Configure dnsmasq pxe server options and fai-chboot if appropriate.

+Without HOST TYPE, disable pxe server and fai server.

+-r         Don't redeploy fai config. For example, if there is a different host
