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

NAME         top

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

SYNOPSIS         top

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

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

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

DESCRIPTION         top

       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         top

       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         top

       Configuration files are read from directories in /etc/, /run/, and
       /usr/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 /usr/lib/. Files in /run/ override files with the same name
       in /usr/lib/.

       Packages should install their configuration files in /usr/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         top

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

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