MODULES-LOAD.D(5)               modules-load.d               MODULES-LOAD.D(5)

NAME
       modules-load.d - Configure kernel modules to load at boot

SYNOPSIS
       /etc/modules-load.d/*.conf

       /run/modules-load.d/*.conf

       /usr/lib/modules-load.d/*.conf

DESCRIPTION
       systemd-modules-load.service(8) reads files from the above directories
       which contain kernel modules to load during boot in a static list. Each
       configuration file is named in the style of
       /etc/modules-load.d/program.conf. Note that it is usually a better idea
       to rely on the automatic module loading by PCI IDs, USB IDs, DMI IDs or
       similar triggers encoded in the kernel modules themselves instead of
       static configuration like this. In fact, most modern kernel modules are
       prepared for automatic loading already.

CONFIGURATION FORMAT
       The configuration files should simply contain a list of kernel module
       names to load, separated by newlines. Empty lines and lines whose first
       non-whitespace character is # or ; are ignored.

CONFIGURATION DIRECTORIES AND PRECEDENCE
       Configuration files are read from directories in /etc/, /run/,
       /usr/local/lib/, and /lib/, in order of precedence, as listed in the
       SYNOPSIS section above. Files must have the the ".conf" extension.
       Files in /etc/ override files with the same name in /run/,
       /usr/local/lib/, and /lib/. Files in /run/ override files with the same
       name under /usr/.

       All configuration files are sorted by their filename in lexicographic
       order, regardless of which of the directories they reside in. If
       multiple files specify the same option, the entry in the file with the
       lexicographically latest name will take precedence. Thus, the
       configuration in a certain file may either be replaced completely (by
       placing a file with the same name in a directory with higher priority),
       or individual settings might be changed (by specifying additional
       settings in a file with a different name that is ordered later).

       Packages should install their configuration files in /usr/lib/
       (distribution packages) or /usr/local/lib/ (local installs). Files in
       /etc/ are reserved for the local administrator, who may use this logic
       to override the configuration files installed by vendor packages. It is
       recommended to prefix all filenames with a two-digit number and a dash,
       to simplify the ordering of the files.

       If the administrator wants to disable a configuration file supplied by
       the vendor, the recommended way is to place a symlink to /dev/null in
       the configuration directory in /etc/, with the same filename as the
       vendor configuration file. If the vendor configuration file is included
       in the initrd image, the image has to be regenerated.

EXAMPLE
       Example 1. /etc/modules-load.d/virtio-net.conf example:

           # Load virtio-net.ko at boot
           virtio-net
