One major distinction I've noticed between Linux and BSD systems is that Linux uses sysctls (aka /proc) in lieu of user-mode tools that retrieve and format data. While this is a reasonable approach when you're distributing only a kernel that's not the case here. For debug info I can buy doing it (e.g. single user and no apps from src/tools), but otherwise we're just adding stuff to the kernel that belongs in apps. Sam
