Just to go off topic another time, after trying it and failing, does the
underlying kernel support multiple routes to the same network (via multiple
destinations) or are the user level programs all correct when not allowing
you to install another route. ie. route and gated will only all add one

I can see nothing in the code, but my kernel code reading skills a rapidly
declining in my old age :-)
