That has been something that has bugged me for a while. Ill take a look
at some possibilities (with just the scripts in rc.d) that might be a
solution to this soon as I get a chance over this next week. It might
just be meaningful to merge the correct areas of the routing script into
the netif scripts restart and relevant sections. Ill look at this as
soon as I get a chance.

Unless if someone has another theory about whether those routes should
be deleted at all if the ifnet address still exists on the parent
interface ?.
