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. | ||
