57 | <para>Network setup is performed by | |

61 | <para>Network files must have the extension | |
62 | <filename>.network</filename>; other extensions are ignored. | |
63 | Networks are applied to links whenever the links appear.</para> | |
64 | ||
65 | <para>The <filename>.network</filename> files are read from the | |
66 | files located in the system network directory | |
12b42c76 | 67 | <filename>/usr/lib/systemd/network</filename>, the volatile |
798d3a52 ZJS |
68 | runtime network directory |
69 | <filename>/run/systemd/network</filename> and the local | |
70 | administration network directory | |
12b42c76 | 71 | <filename>/etc/systemd/network</filename>. All configuration files |
798d3a52 ZJS |
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 | |
12b42c76 | 77 | name in <filename>/usr/lib</filename>. This can be used to |
798d3a52 | 78 | override a system-supplied configuration file with a local file if |
57e27ec0 | 79 | needed. As a special case, an empty file (file size 0) or symlink |
b938cb90 | 80 | with the same name pointing to <filename>/dev/null</filename> |
a8eaaee7 | 81 | disables the configuration file entirely (it is "masked").</para> |

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

93 | well.</para> | |
