These are facts all of us know very well, but implementing this in userspace in a failsafe manner isn't practical. That's what we're discussing. There are things that autoload USB drivers way before udev or similar even get started. For example, the first thing some distributions do is try to load the correct keyboard maps. Guess what that can do? It triggers a load of all of the modular USB host controller drivers in case we have a USB keyboard. The only real solution is in the kernel, because it is the only clean place to trap all of the potential module load events. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
