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

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