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.
Each configuration file shall be named in the style of program.conf. Files in /etc/ override files with the same name in /usr/lib/ and
/run/. 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 from vendor
packages.
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 /etc/modules-load.d/ bearing the same filename.
EXAMPLE
Example 1. /etc/modules-load.d/virtio-net.conf example:
# Load virtio-net.ko at boot
virtio-net
