+HOST A hostname known to the dhcp server, or default for all.
+TYPE One of arch, plain, fai.
+
+
+-r Don't redeploy fai config. For example, if there is a different host
+ that is mid-install.
+
+-a Don't setup pxe, just 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 Setup pxe, then wait like -a.
