-
-                <para><command>systemd-networkd</command> is a system
-                service that manages networks. It detects and configures
-                network devices as they appear, as well as creating virtual
-                network devices.</para>
-
-                <para>Network configurations applied before networkd is started
-                are not removed, and configuration applied by networkd are not
-                removed when networkd exits. This ensures restarting networkd
-                does not cut the network connection, and, in particular, that
-                it is safe to transition between the initrd and the real root,
-                and back.</para>
-        </refsect1>
-
-        <refsect1><title>Configuration Files</title>
-                <para>The configuration files are read from the files located in the
-                system network directory <filename>/usr/lib/systemd/network</filename>,
-                the volatile runtime network directory
-                <filename>/run/systemd/network</filename> and the local administration
-                network directory <filename>/etc/systemd/network</filename>.
-                All configuration files are collectively sorted and processed in lexical order,
-                regardless of the directories in which they live. However, files with
-                identical filenames replace each other. Files in
-                <filename>/etc</filename> have the highest priority, files in
-                <filename>/run</filename> take precedence over files with the same
-                name in <filename>/usr/lib</filename>. This can be used to override a
-                system-supplied configuration file with a local file if needed; a symlink in
-                <filename>/etc</filename> with the same name as a configuration file in
-                <filename>/usr/lib</filename>, pointing to <filename>/dev/null</filename>,
-                disables the configuration file entirely.</para>

+
+    <para><command>systemd-networkd</command> is a system service that
+    manages networks. It detects and configures network devices as
+    they appear, as well as creating virtual network devices.</para>
+
+    <para>To configure low-level link settings independently of
+    networks, see
+    <citerefentry><refentrytitle>systemd.link</refentrytitle><manvolnum>5</manvolnum></citerefentry>.</para>
+
+    <para>Network configurations applied before networkd is started
+    are not removed, and static configuration applied by networkd is
+    not removed when networkd exits. Dynamic configuration applied by
+    networkd may also optionally be left in place on shutdown. This
+    ensures restarting networkd does not cut the network connection,
+    and, in particular, that it is safe to transition between the
+    initrd and the real root, and back.</para>
