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.
