  36     reads files from the above directories which contain kernel
  37     modules to load during boot in a static list. Each configuration
  38     file is named in the style of
  39     <filename>/etc/modules-load.d/<replaceable>program</replaceable>.conf</filename>.
  40     Note that it is usually a better idea to rely on the automatic
  41     module loading by PCI IDs, USB IDs, DMI IDs or similar triggers
  42     encoded in the kernel modules themselves instead of static
  43     configuration like this. In fact, most modern kernel modules are
  44     prepared for automatic loading already.</para>

  50     <para>The configuration files should simply contain a list of
  51     kernel module names to load, separated by newlines. Empty lines
  52     and lines whose first non-whitespace character is # or ; are
  53     ignored.</para>
