Given that builds use a self-hosted runner, that means it is possible to arrange certain directories to kept between runs: speed up the build by keeping the build directory (per architecture) and use ccache (the cache directory is also kept). Cerbero's cache invalidation handles rebuilding packages as needed when source build recipes change.
