- Dockerfile: linux-headers-amd64 meta-package instead of pinned ABI; remove DEBIAN_KERNEL_ABI build-arg (no longer needed at image build time) - build-in-container.sh: drop --build-arg DEBIAN_KERNEL_ABI - build.sh: apt-get update + detect ABI from apt-cache at build time; auto-install linux-headers-<ABI> if kernel changed since image build Image rebuild is now needed only when changing Go version or lb tools, not on every Debian kernel point release.
