 42		Demo/sample use

		This number is intended for use in sample code, as
		well as a general "example" device number.  It
		should never be used for a device driver that is being
		distributed; either obtain an official number or use
		the local/experimental range.  The sudden addition or
		removal of a driver with this number should not cause
		ill effects to the system (bugs excepted.)

		IN PARTICULAR, ANY DISTRIBUTION WHICH CONTAINS A
		DEVICE DRIVER USING MAJOR NUMBER 42 IS NONCOMPLIANT.

		to mounting filesystems over the net, swapping over
		the net, implementing block device in userland etc.
