In essence, it takes either a module name and searches the "right" places for it, or it takes a fully-qualified pathname and loads exactly that module. That's all; anything else is a bug in the implementation and should be fixed. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
