<title>Description</title>
<para><citerefentry><refentrytitle>systemd-modules-load.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
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
<filename>/etc/modules-load.d/<replaceable>program</replaceable>.conf</filename>.
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.</para>

<title>Configuration Format</title>
<para>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.</para>
