24 | .SH "SYNOPSIS" | |
25 | .PP | |
26 | \fInetwork\fR\&.network | |
27 | .SH "DESCRIPTION" | |
28 | .PP | |
29 | Network setup is performed by | |
30 | \fBsystemd-networkd\fR(8)\&. | |
31 | .PP | |
32 | Network files must have the extension | |
33 | \&.network; other extensions are ignored\&. Networks are applied to links whenever the links appear\&. | |
34 | .PP | |
35 | The | |
36 | \&.network | |
37 | files are read from the files located in the system network directory | |
38 | /usr/lib/systemd/network, the volatile runtime network directory | |
39 | /run/systemd/network | |
40 | and the local administration network directory | |
41 | /etc/systemd/network\&. 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 | |
42 | /etc | |
43 | have the highest priority, files in | |
44 | /run | |
45 | take precedence over files with the same name in | |
46 | /usr/lib\&. This can be used to override a system\-supplied configuration file with a local file if needed; a symlink in | |
47 | /etc | |
48 | with the same name as a configuration file in | |
49 | /usr/lib, pointing to | |
50 | /dev/null, disables the configuration file entirely\&. | |
e842803a | 51 | .SH "[MATCH] SECTION OPTIONS" |
60f067b4 JS |
52 | .PP |
53 | The network file contains a | |
54 | "[Match]" | |
55 | section, which determines if a given network file may be applied to a given device; and a | |
56 | "[Network]" | |
e3bff60a | 57 | section specifying how the device should be configured\&. The first (in lexical order) of the network files that matches a given device is applied, all later files are ignored, even if they match as well\&. |
60f067b4 JS |
58 | .PP |
59 | A network file is said to match a device if each of the entries in the | |
