	 *     non-zero values

	 *   * non-matching non-zero ino values be written as non-matching

	 *     non-zero values

	 * Libarchive further ensures that zero ino values get written

	 * as zeroes.  This allows the cpio writer to generate

	 * synthetic ino values for the archive that may be different

	 * than those on disk in order to avoid problems due to truncation.

	 * This is especially needed for odc (POSIX format) that

	 * only supports 18-bit ino values.
