I think that's a good idea, switch the options around so that by default a debug kernel is built and provide an option to build a "production" kernel. I don't think a kernel built with -g is going to be significantly slower or bigger than a standard kernel once stripped and those after maximum performance should know how to go about getting it. The extra disk space for the build would be only problem but given the size of the code base these days most people who have source will have enough spare disk to build a debug kernel. Paul.
