The file /bin/true is a binary file that is ment to be used as a end code for shell script files, so that it ends with an exit code 0 to confirm all went well.
I found this something I think you should take a look at this link
http://portal.suse.com/sdb/en/2004/0...ng_to_26.html, in a few words they say to run this command "generate-modprobe.conf | tee /etc/modprobe.conf" it reads the info at /etc/module.conf, convert it to the file modprobe.conf and finally displays it on the screen.
I'll try to find out some more and then post meanwhile if you find anything say something.
