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