The program is too powerful and cryptic to print reasonable error
IIRC, I've been reading that route shall be replaced with ip, and I
don't like that idea. Route is sufficiently confusing and works fine.

I checked if there is a 'to' in the file when I got that message, and
there was none.

Thanks :) Improving ip so that it can print useful error messages seems
to make more sense than involving a special parser for the particular
purpose of these initscripts.
Knowledge is volatile and fluid. Software is power.
