-.Sh NAME
-.Nm devfs
-.Nd Devices file system
-.Sh DESCRIPTION
-The
-.Nm
-filesystem manages a name space of all devices in the operating environment and
-is mounted during boot on the
-.Pa /devices
-name space.
-.Pp
-The
-.Pa /devices
-name space is dynamic and reflects the current state of accessible devices.
-The names of all attached device instances are present under
-.Pa /devices .
-.Pp
-The content under
-.Pa /devices
-is under the exclusive control of the
-.Nm
-filesystem and cannot be changed.
-.Pp
-The system may be configured to include a device in one of two ways:
-.Bl -enum
-.It
-By means of dynamic reconfiguration
-.Pq DR ,
-using, for example,
-.Xr cfgadm 1M .
-Several different hardware buses such as PCIe and USB automatically discover and
-enumerate devices that they encounter.
-.It
-For devices driven by
-.Xr driver.conf 4
-enumeration, edit the
-.Pa driver.conf
-file to add a new entry, then use
-.Xr update_drv 1M
-to cause the system to re-read the
-.Pa driver.conf
-file and thereby enumerate the instance.
-.El
-.Pp
-The device may be attached through a number of system calls and programs,
-including
-.Xr open 2 ,
-.Xr stat 2 ,
-and
-.Xr ls 1 .
-During device attach, the device driver typically creates minor nodes
-corresponding to the device via
-.Xr ddi_create_minor_node 9F .
-If the attach is successful, one or more minor nodes referring to the device are
-created under
-.Pa /devices .
-.Pp
-Operations like
-.Xr mknod 2 ,
-.Xr mkdir 2 ,
-and
-.Xr creat 2
-are not supported in
-.Pa /devices .
-.Pp
-This file system is not present in a non-global zone.
-.Sh FILES
-.Bl -tag -width Pa
-.It Pa /devices
-Mount point for
-.Nm
-file system in the global zone.
-.El
-.Sh SEE ALSO
-.Xr devfsadm 1M ,
-.Xr vfstab 4 ,
-.Xr attach 9E
-.Sh NOTES
-The
-.Pa /devices
-name space cannot be unmounted.
-.Pp
-All content at or below the
-.Pa /devices
-name space is an implementation
-artifact and subject to incompatible change or removal without notification.
-Generally, user programs should leverage the device name space under
-.Pa /dev .
