  46     reads files from the above directories which contain kernel
  47     modules to load during boot in a static list. Each configuration
  48     file is named in the style of
  49     <filename>/etc/modules-load.d/<replaceable>program</replaceable>.conf</filename>.
  50     Note that it is usually a better idea to rely on the automatic
  51     module loading by PCI IDs, USB IDs, DMI IDs or similar triggers
  52     encoded in the kernel modules themselves instead of static
  53     configuration like this. In fact, most modern kernel modules are
  54     prepared for automatic loading already.</para>

  58     <title>Configuration Format</title>
  59
  60     <para>The configuration files should simply contain a list of
  61     kernel module names to load, separated by newlines. Empty lines
  62     and lines whose first non-whitespace character is # or ; are
  63     ignored.</para>
