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

134 * * non-matching non-zero ino values be written as non-matching
135 * non-zero values
136 * Libarchive further ensures that zero ino values get written
137 * as zeroes. This allows the cpio writer to generate
138 * synthetic ino values for the archive that may be different
139 * than those on disk in order to avoid problems due to truncation.
140 * This is especially needed for odc (POSIX format) that
141 * only supports 18-bit ino values.
