In later releases they saw fit to remove them and they now have udev and hal to do the automatic configuration for you. I bet if there was a rule for udev to create the device you could get it to mount under FC4 & FC5. Alternatively, if you know the specific characteristics of the device you could use mknod to create it manually. > b >
