-
-                <para>Virtual Network Device files must have the extension
-                <filename>.netdev</filename>; other extensions are ignored. Virtual
-                network devices are created as soon as networkd is started. If a netdev
-                with the specified name already exists, networkd will use that as-is
-                rather than create its own. Note that the settings of the pre-existing
-                netdev will not be changed by networkd.</para>
-
-                <para>The <filename>.netdev</filename> 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>Virtual Network Device files must have the extension
+    <filename>.netdev</filename>; other extensions are ignored.
+    Virtual network devices are created as soon as networkd is
+    started. If a netdev with the specified name already exists,
+    networkd will use that as-is rather than create its own. Note that
+    the settings of the pre-existing netdev will not be changed by
+    networkd.</para>
+
+    <para>The <filename>.netdev</filename> 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>
