I'm happy with that - still produces the required effect and removes bloat
from kernel space. Also means it should be easy to revert to default behavior.

My original idea was basically a wrapper much like the way chroot works.
Being able to lock things in some state that was more appropriate for the
program in question. I know that when I set up named/bind on a 2.2 system I
set up with a chroot environment, every time an interface changed state, we
had to restart named so that it could re-bind to the addresses. Being able
to lock the state of those addresses in some way would be brilliant, wether
it's the default or not.
