| 61 | <para>Network files must have the extension <filename>.network</filename>; | |
| 62 | other extensions are ignored. Networks are applied to links whenever the links | |
| 63 | appear.</para> | |
| 64 | ||
| 65 | <para>The <filename>.network</filename> files are read from the files located in the | |
| 66 | system network directory <filename>/usr/lib/systemd/network</filename>, | |
| 67 | the volatile runtime network directory | |
| 68 | <filename>/run/systemd/network</filename> and the local administration | |
| 69 | network directory <filename>/etc/systemd/network</filename>. | |
| 70 | All configuration files are collectively sorted and processed in lexical order, | |
| 71 | regardless of the directories in which they live. However, files with | |
| 72 | identical filenames replace each other. Files in | |
| 73 | <filename>/etc</filename> have the highest priority, files in | |
| 74 | <filename>/run</filename> take precedence over files with the same | |
| 75 | name in <filename>/usr/lib</filename>. This can be used to override a | |
| 76 | system-supplied configuration file with a local file if needed; a symlink in | |
| 77 | <filename>/etc</filename> with the same name as a configuration file in | |
| 78 | <filename>/usr/lib</filename>, pointing to <filename>/dev/null</filename>, | |
| 79 | disables the configuration file entirely.</para> | |

86 | <para>The network file contains a <literal>[Match]</literal> section, |
| 87 | which determines if a given network file may be applied to a given device; | |
| 88 | and a <literal>[Network]</literal> section specifying how the device should | |
| 89 | be configured. The first (in lexical order) of the network files that | |
| 90 | matches a given device is applied.</para> | |
