+Usage: ${0##*/} [OPTIONS] [HOST] [TYPE]
+Configure dnsmasq boot options and fai-chboot if appropriate. This is
+not general purpose, it has code specific to dhcp servers I run.
 
-Without HOST TYPE, disable  server and fai server.
+Without TYPE, disable  server and fai server. In that case, HOST is only
+needed for fsf office network.
 
 HOST       A hostname known to the dhcp server, or default for all.
 TYPE       One of arch, parabola, plain, fai.
 
--d         Don't alter dhcp config. Only make sense for fai type, and on network
-           other than home network.
--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.
--S         sets FAI_ACTION=sysinfo, see myfai-chboot for more info.
+-d         Don't alter dhcp config. Only make sense for fai type, and on network
+           other than home or fsf.
 -k         Pass -k to myfai-chboot.
+-r         Don't redeploy fai config. For example, if there is a different host
+           that is mid-install.
+
+-S         sets FAI_ACTION=sysinfo, see myfai-chboot for more info.
 -w         Setup pxe, then wait like -a.
