          <link xlink:href="options.html#opt-services.wordpress.webserver"><literal>services.wordpress.webserver</literal></link>.
          Currently <literal>httpd</literal> and
          <literal>nginx</literal> are supported. The definitions of
          wordpress sites should now be set in

          Sites definitions that use the old interface are automatically
          migrated in the new option. This backward compatibility will
          be removed in 22.05.
