// environment, rather than from the pipeline itself. Without a specified
// build environment, the build host's root filesystem would be used, which
// is not predictable nor reproducible. For the purposes of building the
// build pipeline, we do use the build host's filesystem, this means we should
// make minimal assumptions about what's available there.
