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>
72 <title>Configuration Format</title>
74 <para>The configuration files should simply contain a
75 list of kernel module names to load, separated by
76 newlines. Empty lines and lines whose first
77 non-whitespace character is # or ; are ignored.</para>
