16 systemd-modules-load.service(8) reads files from the above directories
17 which contain kernel modules to load during boot in a static list. Each
18 configuration file is named in the style of
19 /etc/modules-load.d/program.conf. Note that it is usually a better idea
20 to rely on the automatic module loading by PCI IDs, USB IDs, DMI IDs or
21 similar triggers encoded in the kernel modules themselves instead of
22 static configuration like this. In fact, most modern kernel modules are
23 prepared for automatic loading already.
24
26 The configuration files should simply contain a list of kernel module
27 names to load, separated by newlines. Empty lines and lines whose first
28 non-whitespace character is # or ; are ignored.
29
31 Configuration files are read from directories in /etc/, /run/, and
32 /usr/lib/, in order of precedence. Each configuration file in these
33 configuration directories shall be named in the style of filename.conf.
34 Files in /etc/ override files with the same name in /run/ and
35 /usr/lib/. Files in /run/ override files with the same name in
36 /usr/lib/.
37
38 Packages should install their configuration files in /usr/lib/. Files
39 in /etc/ are reserved for the local administrator, who may use this
40 logic to override the configuration files installed by vendor packages.
41 All configuration files are sorted by their filename in lexicographic
42 order, regardless of which of the directories they reside in. If
43 multiple files specify the same option, the entry in the file with the
44 lexicographically latest name will take precedence. It is recommended
45 to prefix all filenames with a two-digit number and a dash, to simplify
46 the ordering of the files.
47
48 If the administrator wants to disable a configuration file supplied by
49 the vendor, the recommended way is to place a symlink to /dev/null in
50 the configuration directory in /etc/, with the same filename as the
51 vendor configuration file.
