MODULES-LOAD.D(5)                               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
          ".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
