 Usage: ${0##*/} [OPTIONS] [HOST TYPE]
-One line description
+Configure dnsmasq pxe server options and fai-chboot if appropriate.

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

+HOST       A hostname known to the dhcp server, or default for all.
+TYPE       One of arch, plain, fai.
 
-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. For example, if there is a different host
            that is mid-install.
--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.

 -h|--help  Print help and exit
 
 
+Note, when switching between plain and arch, you will need to

+ssh wrt
+cd /mnt/usb
+rm tftpboot
+ln -s <arch/debian iso dir> tftpboot
