Actually, we're inconsistent (who'd have guessed? :-)). For instance if CONFIG_CURSES isn't defined then we print an error if you try to use the curses option, similarly for iscsi, slirp related options, tpmdev, and others. But there are also many options where (as you note) we just silently ignore them, and even a few where we print a warning but continue to boot (eg some of the networking config options). -- PMM
