+       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.
