	The sysfs filesystem is a virtual filesystem that the kernel uses to
	export internal kernel objects, their attributes, and their
	relationships to one another.

	Users can use sysfs to ascertain useful information about the running
	kernel, such as the devices the kernel has discovered on each bus and
	which driver each is bound to. sysfs can also be used to tune devices
	and other kernel subsystems.

	Some system agents rely on the information in sysfs to operate.
	/sbin/hotplug uses device and object attributes in sysfs to assist in
	delegating policy decisions, like persistently naming devices.

	sysfs is currently used by the block subsystem to mount the root
	partition.  If sysfs is disabled you must specify the boot device on
	the kernel boot command line via its major and minor numbers.  For
	example, "root=03:01" for /dev/hda1.

	Designers of embedded systems may wish to say N here to conserve space.
