+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.
