NAME
       devfs - Devices file system

DESCRIPTION
       The  devfs filesystem manages a name space of all devices under the So-
       laris operating environment and is mounted during boot on the  /devices
       name space.

       The  /devices  name  space is dynamic and reflects the current state of
       accessible devices under	the Solaris operating environment.  The	 names
       of all attached device instances	are present under /devices.

       The  content under /devices is under the	exclusive control of the devfs
       filesystem and cannot be	changed.

       The system may be configured to include a device	in one of two ways:

		 By means of dynamic reconfiguration (DR), using, for example,
		 cfgadm(1M).

		 For  devices  driven  by driver.conf(4) enumeration, edit the
		 driver.conf file to add a new entry, then use	update_drv(1M)
		 to  cause  the	 system	 to  re-read  the driver.conf file and
		 thereby enumerate the instance.

       The device may be attached through a number of system  calls  and  pro-
       grams,  including open(2), stat(2) and ls(1). During device attach, the
       device driver typically creates minor nodes corresponding to the	device
       via ddi_create_minor_node(9F). If the attach is successful, one or more
       minor nodes referring to	the device are created under /devices.

       Operations like mknod(2), mkdir(2) and creat(2) are  not	 supported  in
       /devices.

NOTES
       The /devices name space cannot be unmounted.

       All  content  at	 or below the /devices name space is an	implementation
       artifact	and subject to incompatible change or removal without  notifi-
       cation.
