| * 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 |
