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

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