While packaging of hamradio software in Debian is the responsibility of the Debian Hamradio Maintainers, the pure blend project does provide the following tools that may be useful to packagers:
Metapackages Source Code
git clone https://salsa.debian.org/blends-team/hamradio cd hamradio ; make dist gbp buildpackage
Live DVD Source Code
git clone https://salsa.debian.org/blends-team/blends-images.git cd blends-images/images/hamradio-amd64 lb config sudo lb build
