I don't agree that mknod is user space.
On other systems I've had to do it both ways, creating the inodes within the kernel or using a script after creating the device.
In my experience with dynamic allocation of major numbers, especially if you have switchs that selectively enable certain features (i.e. use different minor devices), it has been a lot easier for maintenance to have the code in the driver rather than a separate script.
Many of the other UNIX systems that started with requiring you to run a script have changed to having the driver create the inodes.
I'm not sure which way I'll go right now, creating the script in /proc or trying to do it from kernel. I do know which way I would prefer to do it.
