+usage: ${0##*/} [OPTIONS] [HOSTNAME|IP|default]
+
+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.
+
+Usng this, you can boot into fai with pxe-kexec without changing
+the dhcp server.
+
+Argument 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.
+-h|--help Print help and exit.
