-+config DEVFS_FS
-+ bool "/dev file system support (OBSOLETE)"
-+ depends on EXPERIMENTAL
-+ 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.
-+
-+ If unsure, say N.
-+
-+config DEVFS_MOUNT
-+ bool "Automatically mount at boot"
-+ depends on DEVFS_FS
-+ help
-+ 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.
-+
-+ If unsure, say N.
-+
-+config DEVFS_DEBUG
-+ bool "Debug devfs"
-+ depends on DEVFS_FS
-+ help
-+ If you say Y here, then the /dev file system code will generate
-+ debugging messages. See the file
-+ <file:Documentation/filesystems/devfs/boot-options> for more
-+ details.
-+
-+ If unsure, say N.
