+                <para>A unit configuration file whose name ends in

+                swap device or file for memory paging controlled and
+                supervised by systemd.</para>
+
+                <para>This man page lists the configuration options
+                specific to this unit type. See

+                for the common options of all unit configuration
+                files. The common configuration items are configured
+                in the generic [Unit] and [Install] sections. The swap
+                specific configuration options are configured in the
+                [Swap] section.</para>
+
+                <para>Additional options are listed in
+                <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>5</manvolnum></citerefentry>,

+
+                <para>Swap units must be named after the devices
+                or files they control. Example: the swap device
+                <filename>/dev/sda5</filename> must be configured in a
+                unit file <filename>dev-sda5.swap</filename>. For

+                implicitly acquire a conflicting dependency to

+                for details). Swaps listed in
+                <filename>/etc/fstab</filename> will be converted into
+                native units dynamically at boot and when the
