Because I've got static routes, and I know exactly what they are.

The box(es) which inspired this sit on a private network, and once they are
brought into service, the routes never change.  However, there is a command from
our gui to manually drop and raise the ethernet link (just in case something
goes wrong and can't be handled automatically) and it would simplify our code
greatly if the routes that are automatically deleted would be automatically put
back.

In this case, my software *is* essentially the routing daemon, and I want it to
be simpler to maintain.

I think the concept is simple: I added some routes, and I think they should stay
there until I remove them or the machine reboots.  Doesn't this seem like a
logical behaviour?
