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