+ help
+ 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.
