+         With this option modprobe does not require modules.dep file
+         and does not use /etc/modules.conf file.
+         It scans module files in /lib/modules/`uname -r` and
+         determines dependencies and module alias names on the fly.
+         This may make module loading slower, most notably
+         when one needs to load module by alias (this requires
+         scanning through module _bodies_).
+
+         At the first attempt to load a module by alias modprobe
+         will try to generate modules.dep.bb file in order to speed up
+         future loads by alias. Failure to do so (read-only /lib/modules,
+         etc) is not reported, and future modprobes will be slow too.
+
+         NB: modules.dep.bb file format is not compatible
+         with modules.dep file as created/used by standard module tools.
+
+         Additional module parameters can be stored in
+         /etc/modules/$module_name files.
+
+         Apart from modprobe, other utilities are also provided:
