[arch-releng] [PATCH 2/2] [configs/releng] Introducing syslinux/ifpxelinux.lua

[Gerardo Exequiel Pozzi]

ifpxelinux.lua is a trivial Lua script that I made to work like ifcpu64.c32.
In that way we can have two differents syslinux menus depending if booting from
PXE or from non-PXE.

* By default NBD PXE option is selected for booting on timeout.
* As server (NDB/NFS/HTTP/FTP) is used the same ip from pxeserver.
