-- Refers to "rmmod -r", but rmmod has no -r option. -- Should say that it looks for /etc/modules.conf BEFORE /etc/conf.modules I had a modules.conf and then Red Hat tools made conf.modules. The result was unexpected behavior and confusion. -- "list all" should be "lists all".
rmmod does have a "-r" switch in recent versions. The distro is now using modules.conf as opposed to conf.modules.
