## <module name="devices" layer="kernel">
## <description>
##	<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>
