+    modules to load during boot in a static list. Each configuration
+    file is named in the style of
+    <filename>/etc/modules-load.d/<replaceable>program</replaceable>.conf</filename>.
+    Note that it is usually a better idea to rely on the automatic
+    module loading by PCI IDs, USB IDs, DMI IDs or similar triggers
+    encoded in the kernel modules themselves instead of static
+    configuration like this. In fact, most modern kernel modules are
+    prepared for automatic loading already.</para>

+    and lines whose first non-whitespace character is # or ; are
