* short, libarchive needs to know whether a "hardlink entry"
* is going to overwrite the contents so that it can know
* whether or not to open the file for writing. This implies
* that there is a fundamental semantic difference between an
* entry with a zero size and one with a non-zero size in the
* case of hardlinks and treating the hardlink case
* differently from the regular file case is just asking for
* trouble. So, a zero size must always mean that no data
* will be accepted, which is consistent with the file size in
