+# NOTE about permissions in OpenZaurus
+# 	The devices in question here by default
+#	are accessible to everyone in the group in
+#	question.  We wish to ensure that, as a policy
+#	choice, a login to opie makes access to these
+#	devices exclusive by 1) changing device ownership
+#	to the user, and 2) removing group access.
+#
+#	A better implementation would probably be to store
+#	existing device permissions at load time, and restore
+#	them at exit, rather than making assumptions about
+#	user/group ownership, or permissions.
