+ bool "/dev file system support (OBSOLETE)"

|
|
+ help
|
|
+ This is support for devfs, a virtual file system (like /proc) which
|
|
+ provides the file system interface to device drivers, normally found
|
|
+ in /dev. Devfs does not depend on major and minor number
|
|
+ allocations. Device drivers register entries in /dev which then
|
|
+ appear automatically, which means that the system administrator does
|
|
+ not have to create character and block special device files in the
|
|
+ /dev directory using the mknod command (or MAKEDEV script) anymore.
|
|
+
|
|
+ This is work in progress. If you want to use this, you *must* read
|
|
+ the material in <file:Documentation/filesystems/devfs/>, especially
|
|
+ the file README there.
|
|
+
|
|
+ Note that devfs no longer manages /dev/pts! If you are using UNIX98
|
|
+ ptys, you will also need to mount the /dev/pts filesystem (devpts).
|
|
+
|
|
+ Note that devfs has been obsoleted by udev,
|
|
+ <http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.
|
|
+ It has been stripped down to a bare minimum and is only provided for
|
|
+ legacy installations that use its naming scheme which is
|
|
+ unfortunately different from the names normal Linux installations
|
|
+ use.

|
|
+ This option appears if you have CONFIG_DEVFS_FS enabled. Setting

+ this to 'Y' will make the kernel automatically mount devfs onto /dev
|
|
+ when the system is booted, before the init thread is started.
|
|
+ You can override this with the "devfs=nomount" boot option.
