I often find that parsing these things gets gross in shell, and we
don't get to use perl or such in /etc/rc and friends (perhaps a good
thing!) Given this, I'd like to see how ugly an implementation of what you
propose ends up looking. Perhaps you could provide one? Remember that
the thing also has to handle routing the interface aliases and the
like, so it is going to have to recognise which lines contain
addresses that need to be routed to localhost.

Just to understand, I was trying to provide the functionality in a
minimally intrusive way -- it seemed like a very simple way to add the
functionality, and the functionality seems to be of common use these

It can't be that simple, unfortunately, because of the need to do
things like setting up routing.
