18 # Setup dhcp server to point to tftp server,

22 # default distro is the base debian/fedora type. others are fai & arch.

31 Usage: ${0##*/} [OPTIONS] [HOST TYPE]
32 Configure dnsmasq pxe server options and fai-chboot if appropriate.
34 Without HOST TYPE, disable pxe server and fai server.
36 HOST A hostname known to the dhcp server, or default for all.
37 TYPE One of arch, plain, fai.
40 -r Don't redeploy fai config. For example, if there is a different host
43 -a Don't setup pxe, just Wait for 2 dhcp acks, then disable the pxe
44 server after a delay. First ack is for pxe boot, 2nd ack is
45 for os boot. Sometimes on debian, there is a 3rd one shortly
46 after the 2nd. I can't remember exactly why this caused a
47 problem, but I'm hoping the sleep will take care of it.
48 -S Pass -S to fai-chboot.
49 -w Setup pxe, then wait like -a.
50 -h|--help Print help and exit
53 Note, when switching between plain and arch, you will need to
