Is this just file size or does it take up > significantly more memory as well? You would install two kernels: /kernel and /kernel.debug. The first one is a normal kernel (but no debugging info) and this is the one you run. So no more memory is used (except on your disk). The second you only need as a debug reference for the first when you get a core dump. > - Does a debug kernel impart any performance hit? No... the same code is being executed as before. -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
