This will drag in most off the ddx layer I'm afraid, so its really not practical. Lets step back for a moment, this is clearly the wrong solution to everything, what exactly is it you want to do or want to accomplish?? Lets see if we can come up with another way of doing that... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
