149 The sysfs filesystem is a virtual filesystem that the kernel uses to
150 export internal kernel objects, their attributes, and their
151 relationships to one another.
152
153 Users can use sysfs to ascertain useful information about the running
154 kernel, such as the devices the kernel has discovered on each bus and
155 which driver each is bound to. sysfs can also be used to tune devices
156 and other kernel subsystems.
157
158 Some system agents rely on the information in sysfs to operate.
159 /sbin/hotplug uses device and object attributes in sysfs to assist in
160 delegating policy decisions, like persistently naming devices.
161
162 sysfs is currently used by the block subsystem to mount the root
163 partition. If sysfs is disabled you must specify the boot device on
164 the kernel boot command line via its major and minor numbers. For
165 example, "root=03:01" for /dev/hda1.
