+config BUSYBOX_CONFIG_MODPROBE_SMALL
+	bool "Simplified modutils"
+	default n
+	help
+	  Simplified modutils.
+
+	  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.
