I think this would be the better solution in general, but I have one
thing to add with it.
ifconfig should really get deprecated. The 'ip' tool of sys-apps/iproute
has long been noted as mostly superior in functionality (there are some
obscure, obsolete commands in ifconfig that I have never heard of
being used in recent times). 

'ip' also provides a single tool for easily doing things that would take
a few other commands.

One particullar distinction is the seperation of the link and address
layers, which are mostly synonymous in ifconfig.

One other thing to consider in this, is possible integration of
zeroconf (http://www.zeroconf.org/).

On any system, IPv4 network will practially always exist, even if it is
only on the loopback interface.
