- 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_).
+ Build smaller (~1.5 kbytes), simplified module tools.
- 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.
+ This option by itself does not enable any applets -
+ you need to select applets individually below.

- with modules.dep file as created/used by standard module tools.
