Together with the Device ID this uniquely identifies a file in this dump. In the case of hard links, two objects may appear with the same (dev,ino) combination. A value of 0 is assumed if this field is absent. This is currently (ncdu 1.9-1.13) not a problem as long as the hlnkc field is false, otherwise it will consider everything with the same dev and empty ino values as a single hardlinked file. Accepted values are in the range of 0 <= ino < 2^64." For us, it's just an arbitrary counter to mark each znode as a unique entity. ---
