This caused issues in various areas where Pat (and/or dependencies) relied on os.TempDir() store temporary files. E.g. when running `pat updateforms`. We can't do this inside the build container, as there is no way of specifying file permissions when doing COPY --from. The solution (inspired by the distroless images) is to ADD a pre-prepared tarball with the correct file permissions. `mkdir -m 01777 tmp && tar --owner=root --group=root -cf tmp.tar tmp`
