-Usage: ${0##*/} [OPTIONS] TYPE [HOST]
-One line description
-
-TYPE is one of arch, plain, fai, or : for no pxe server.
-HOST makes the pxe server only for that specific host
-
--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.
+Usage: ${0##*/} [OPTIONS] [HOST TYPE]
+Configure dnsmasq pxe server options and fai-chboot if appropriate.
+
+
+Without HOST TYPE, disable pxe server and fai server.
+TYPE is one of arch, plain, fai.
+HOST is a hostname known to the dhcp server, or default for all
+Note, when switching between plain and arch, you will need to
+do something like:
+ssh wrt
+cd /mnt/usb
+rm tftpboot
+ln -s <arch/debian iso dir> tftpboot
+
+
+-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.
