  59                 reads files from the above directories which contain
  60                 kernel modules to load during boot in a static list.
  61                 Each configuration file is named in the style of
  62                 <filename>/etc/modules-load.d/<replaceable>program</replaceable>.conf</filename>. Note
  63                 that it is usually a better idea to rely on the
  64                 automatic module loading by PCI IDs, USB IDs, DMI IDs
  65                 or similar triggers encoded in the kernel modules
  66                 themselves instead of static configuration like
  67                 this. In fact, most modern kernel modules are prepared
  68                 for automatic loading already.</para>
