I don't think it has to be or should be in the kernel. Basically, /dev/dk3 gets created or is used by the kernel. A daemon is notified (*cough* udevd) and that scans the device properties, finds the UUID and creates /dev/uuid/2345324523453245. It also finds the label and creates /dev/label/my-usb-stick. The latter is what you put in /etc/fstab. Joerg
