+         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

+
+         NB: modules.dep.bb file format is not compatible
