In addition, you should know that the kernel and device drivers may automatically 
create device special files in the /dev directory. The mtd layer is one of the 
components that does this. Automatic /dev file creation is normally done through 
the kernel hotplug framework. You can read more about this at kernel.org 
(http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html) or the Wikipedia 
article http://en.wikipedia.org/wiki/Udev.
