I'm not an expert, having done this for the first time yesterday, but the short answer is like this: cd ^/release/; ./release.sh -c arm64/RPI3.conf Note that this will build a complete chroot for the build system, including ports, with sources that it checks out, and then builds the target system. The chroot is built in /scratch. I built from head on amd64. Mike
