Would it be possible to add a flag in make.conf to allow a kernel.debug to be installed along side the regular kernel? This way people can set things up once and not having to worry about digging around for a kernel with symbols if a panic should occur. I know there's there's an installkernel.debug target under /usr/src, but I'm unclear as to what it does. Does it install both the regular and debugging kernels, or just the debugging one? Just a suggestion.
