+
+ 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:
+ - insmod is an alias to modprobe
+ - rmmod is an alias to modprobe -r
+ - depmod generates modules.dep.bb
+
+ As of 2008-07, this code is experimental. It is 14kb smaller
+ than "non-small" modutils.
