The devfs filesystem manages a name space of all devices under the Solaris 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 can not be changed.
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 notification.
