What happens is that the moment the DHCP client tries to add the gateway
route, there is no route to the gateway itself. That causes it to reject
the gateway route.
If you manually add a route to the gateway, then sure you can also
manually add the gateway route.
Hm, I can make ifupdown force the addition of the gateway route, but
only for statically configured interfaces. For inet dhcp, it's the DHCP
client itself that adds the routes, ifupdown has no influence over it.
One could modify /sbin/dhclient-script to do that though...
