+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.
