I would recommend to add a "-f" option anyway. It is way too easy to set (as I did yesterday) "dumpdev=/dev/ad0s2" in your rc.conf and be very surprised after a crash. If you really want to do this, you could do it with a "dumpon_flags=-f". Sam To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
