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

  46     <title>Configuration Format</title>
  47
  48     <para>The configuration files should simply contain a list of
  49     kernel module names to load, separated by newlines. Empty lines
  50     and lines whose first non-whitespace character is # or ; are
  51     ignored.</para>
