i don't really use netcfg myself, but the explanation Thomas has given
above doesn't seem too arch specific; and from a quick glance at
http://wiki.archlinux.org/index.php/Netcfg it seems netcfg is not - or
at least should not have to be - very arch-specific. maybe we should
treat it more as a separate project (like pacman or libui-sh) and
integrate it into our initscripts like we already do.

Also there's this duality for a while that our networking initscripts
are really basic and limited, and netcfg should fix all that, but it's
not very "official" or "recommended" or whatever. maybe it's time to
unify things into 1 networking configuration utility (which, still
doesn't need to be bound to arch linux), it will make things easier for
everyone. so we could only use netcfg and drop the other limited stuff.
