For the case where /usr/src is the same branch you can do this (I do this to test-compile cross-builds where the kernel tree isn't in /usr/src/sys): % cd /usr/src % make TARGET_ARCH=amd64 kernel-toolchain % make TARGET_ARCH=amd64 buildkernel KERNSRCDIR=/home/jhb/work/p4/smpng \ NO_KERNELCLEAN=yes -- John Baldwin
