## <p>
## This module creates the device node concept and provides
## the policy for many of the device files. Notable exceptions are
## the mass storage and terminal devices that are covered by other
## modules.
## </p>
## <p>
## This module creates the concept of a device node. That is a
## char or block device file, usually in /dev. All types that
## are used to label device nodes should use the dev_node macro.
## </p>
## <p>
## Additionally, this module controls access to three things:
## <ul>
## <li>the device directories containing device nodes</li>
## <li>device nodes as a group</li>
## <li>individual access to specific device nodes covered by
## this module.</li>
## </ul>
