Ollama. Empacota seguindo o fluxo do Dockerfile oficial:
- CMake presets por componente (CPU, Vulkan, ROCm/HIP) com 'cmake --install ... --component ...'
- Binário Go compilado com -buildmode=pie
- Systemd (ollamad.service), sysusers, configuração em /etc/ollamad
- ld.so.conf.d apontando /usr/lib/ollama

%changelog
* Sun Nov 02 2025 Moacyr Prado <you@example.org> - 0.12.7-7
- Alinha ao Dockerfile oficial: presets CPU/Vulkan/ROCm6 com install por component (CPU/Vulkan/HIP)
- Usa staging DESTDIR e copia para buildroot no %install
- Compila Go com -buildmode=pie; mantém systemd/sysusers/conf/ldconfig
- Subpacotes -vulkan e -rocm ligados via bconds
