-
-    <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
