Yup. And if you put a line in route-ethN like:

default via 10.0.0.1 dev ethN from 10.0.0.0/24

you're in for a rude shock; running "ip route show" after bringing up
ethN will show something like:

default via 10.0.0.1 dev ethN

...having stripped the key "from 10.0.0.0/24" portion. I ran into
similar problems with "table SomeTable".
