I'd like to lay out why I > think that is. One final comment: Can you implement a persistent device naming scheme using devfs today? If so, please show me how you would: - always name a USB printer the same /dev name no matter when it is discovered by the USB core (before or after any other USB printer.) - always name your SCSI disk the same /dev name no matter where in the scsi probe sequence it is (yank it out and plug it into another place in your scsi rack.) This is the main problem that udev solves. The fact that it also gives you a dynamic /dev is just extra goodness. 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/ | ||||||||||
