The argument for not using ifconfig, route and friends is that they vary too
much between platforms. No so much on the BSD's, but it is on Linux.
I actually save code by writing it in C - one BSD implementation currently
fits all, one Linux implementation currently fits all. And the BSD/Linux
specific code isn't really that much.
For an idea, look how many scripts that dhclient ships with and how much code
could be re-used.
