Here's my /etc/init.d/network on a machine at home. All that needs to
change is the gateway and the network. I think Debian ought to put a
test on the NETWORK variable as well as GATEWAY.

Ignore all the aliasing stuff. The first is for a laptop, the second is
to fool my wife's machine into thinking I'm her employer's gateway when 
it's connected to mine at home.
