    release: Enable installing packages as a non-root user
    
    Provide variables, PKG_REPOS_DIR and PKG_REPO_NAME, to allow the user to
    configure the source package repository.  Configure pkg to emit added
    files to a metalog which gets concatenated with the main metalog
    immediately before we build the root filesystem.
