The "some of you" was me, if I recall the complete discussion thread. :) While it's true MAKEDEV needs to create the device special files, the device special files that are stored there need to be writeable. Here's one key example: You mount(8) a device special file when you mount a filesystem. All write operations to that mounted filesystem are directed through the device special file. ---- While you won't run MAKEDEV while the system is up and running, take a look at the MAKEDEV(8) man page. You'll see a lot of device special files that will need to be writeable.
