</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>
