With 6.x and earlier it would keep them in the /usr/obj hierarchy but not deposit them into /boot/kernel. Not saying one is better than the other (although it is nice to have the symbols in an easy-to-find directory when needed), but that would explain why your average kernel now needs 3-4x the space if you've enabled kernel debugging. -Proto
