So no "scanning" happens unless specificically asked for. And as mentioned, udev can work just fine without sysfs enabled at all now, with the exception of some custom rules for some devices. thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
