It wouldn't be hard to drop permissions in innd immediately at the top of
main() if it discovers that it's run as root instead of just bailing out.
It's always hard to figure out the right balance between attempting to
self-correct (and possibly getting things wrong) versus just telling the
user something looks wrong and leaving it to them to sort out.  But maybe
it would be less confusing to just switch to the right user if we can.
