I was talking about with just a plain file system. I read in a install guide somewhere when I was installing ages ago that having /boot on a separate partition, and not always mounted, was a good security practice. That way no one could alter the kernel since it was not mounted. I do agree that if a person was on the system and able to get root access, they could them mount the /boot partition as well. I never was really sure why this was thought to work. I used a separate /boot because for a while I was dual booting Mandrake and Gentoo. Old habit now I guess. Dale :-) :-)
