</p><p>Virtual Network Device files must have the extension
<code class="filename">.netdev</code>; 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.</p><p>The <code class="filename">.netdev</code> files are read from the
files located in the system network directory
<code class="filename">/usr/lib/systemd/network</code>, the volatile
runtime network directory
<code class="filename">/run/systemd/network</code> and the local
administration network directory
<code class="filename">/etc/systemd/network</code>. 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
<code class="filename">/etc</code> have the highest priority, files in
<code class="filename">/run</code> take precedence over files with the same
name in <code class="filename">/usr/lib</code>. This can be used to
override a system-supplied configuration file with a local file if
needed; a symlink in <code class="filename">/etc</code> with the same name
as a configuration file in <code class="filename">/usr/lib</code>, pointing
to <code class="filename">/dev/null</code>, disables the configuration file
entirely.</p></div><div class="refsect1"><a name="idm140504091078832"></a><h2 id="Supported netdev kinds">Supported netdev kinds<a class="headerlink" title="Permalink to this headline" href="#Supported%20netdev%20kinds"></a></h2><p>The following kinds of virtual network devices may be
