Files
	kmsg.c
	/dev/kmsg (character device 1, 11): the kernel's messages.
	memdev.c
	The memory devices: the character devices of major 1, as on Linux.
	memdev.h
	null.c
	/dev/null (character device 1, 3): reading it gives nothing, the end of the file at once, and what is written to it is thrown away.
	random.c
	Random numbers: /dev/random and /dev/urandom (character devices 1, 8 and 1, 9), which are the same, and random_get() for the kernel.
	zero.c
	/dev/zero (character device 1, 5): reading it gives as many zero bytes as asked for, and what is written to it is thrown away.
