  28 Sets up tftp pxe config and nfs server on host "faiserver".
  29
  30 If our kernel has no nfs support, uses apache intead of nfs, and depends
  31 on another repo of Ian Kelling, basic-https-conf, where the file is at
  32 /a/exe/web-conf.
  33
  34 Using this, you can boot into fai with pxe-kexec without changing the
  35 dhcp server. Note, if you are booting using fai-cd, the pxe config does
  36 nothing, and only flags affecting FAI_ACTION will have any affect. You
  37 can change the fai flags in the grub config, for example in
  38 ./grub.cfg.autodiscover, or at runtime by editing a grub menu option.
  39 We could probably also set FAI_FLAGS the same way we set FAI_ACTION,
  40 but I haven't tried it.
  41
  42 HOSTNAME|IP|default  Sets the host to enable it for.  No argument
  43                      disables pxe config for all hosts, but leaves nfs
  44                      server alone. Use faiserver-disable to disable the
  45                      nfs server.
  46
  47 -S          sets FAI_ACTION=sysinfo, and remove fai flag reboot.
  48             Usefull for doing a system recovery. It reboots automatically anyways :(
  49 -k          Add serial port output for kgped16
  50 -i          sets FAI_ACTION=inventory and remove fai flag reboot.
  51             I'm not sure what this is usefull for.
  52 -b          Setup bonded ethernet.
  53 --no-r      Tell fai-chboot not to reboot when its done. This is implied by -i and -S.
  54 -h|--help   Print help and exit.
