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
       ".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
