modules-load.d - Configure kernel modules to load at boot
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.
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
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 1. /etc/modules-load.d/virtio-net.conf example:
# Load virtio-net.ko at boot
