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/, and /lib/, in order of
       precedence. Each configuration file in these configuration directories shall be named in
       the style of filename.conf. Files in /etc/ override files with the same name in /run/ and
       /lib/. Files in /run/ override files with the same name in /lib/.

       Packages should install their configuration files in /lib/. Files in /etc/ are reserved
       for the local administrator, who may use this logic to override the configuration files
       installed by vendor packages. 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. 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
