Pulp expects custom metadata files to have a specific format for filenames: -.

During sync or pulp-2to3-migration, users get FileNotFoundError: [Errno 2] No such file or directory: ' ' because the filename is only a checksum :/, which we remove to determine the filename, so the path we detect becomes an empty string.
