Ah :-) thanks for explaining.
BTW, I believe the hardlink concept is one of worst original UNIX features. COW copy would make sense, but hardlinks are usually more trouble than worth.Well, the main problem is that you can make hard links to files you don't own. We should enable the kernel's hard link restrictions feature in NixOS...
