Yup, it's real easy. Just list all the config files on the KERNCONF line like so: KERNCONF=GURU GENERIC You can list more than two, and you don't have to build GENERIC if you don't want to. The first one listed - in this case GURU - will be the one installed by "installkernel". You probably want to set MODULES_WITH_WORLD=true as well, otherwise it will build the modules when it builds each kernel, which is probably a waste of time. This also means that you don't install modules until you do the installworld, which can cause interesting problems. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
