All hard-links to an inode share the same access permissions, that of the inode. To delete, i. Therefore it's irrelevant which privileges were used to create the hard-link. They may just happen to still be the same as at the time of creation. Very misleading.

This doesn't cover the situation where the file is open when the last link is unlink ed.

Having data without a pointer is useless, too. Because there is no way you can open the file. You lost your handle to it but it's there. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
