  61     <para>Network files must have the extension

  63     Networks are applied to links whenever the links appear.</para>
  64
  65     <para>The <filename>.network</filename> files are read from the

  72     are collectively sorted and processed in lexical order, regardless
  73     of the directories in which they live. However, files with
  74     identical filenames replace each other. Files in
  75     <filename>/etc</filename> have the highest priority, files in
  76     <filename>/run</filename> take precedence over files with the same
  77     name in <filename>/usr/lib</filename>. This can be used to
  78     override a system-supplied configuration file with a local file if
  79     needed; a symlink in <filename>/etc</filename> with the same name
  80     as a configuration file in <filename>/usr/lib</filename>, pointing
  81     to <filename>/dev/null</filename>, disables the configuration file
