You might want to use portal instead of union, for that matter. I've set up sendmail inside of a chrooted environment using portal for read only access to /etc (which lies on a different partition, so hard links to appropriate files are impossible). -- Brian Cully ``And when one of our comrades was taken prisoner, blindfolded, hung upside-down, shot, and burned, we thought to ourselves, `These are the best experiences of our lives''' -Pathology (Joe Frank, Somewhere Out There) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
