+                for the common options of all unit configuration
+                files. The common configuration items are configured
+                in the generic [Unit] and [Install] sections. The
+                automount specific configuration options are configured
+                in the [Automount] section.</para>
+
+                <para>Automount units must be named after the file
+                paths they reflect. Example: the automount point
+                <filename>/home/lennart</filename> must be configured
+                in a unit file
+                <filename>home-lennart.automount</filename>. For
+                details about the escaping logic used to convert a

+                for details) must exist which is activated when the
+                automount path is accessed. Example: if an automount
