My (simple) question is:
What is "hard links"? never really heard of it and googles no help either.
Am I missing something?
You can think of hard links as of reference variables in php:
$a = 5; $b =& $a;
$b would be a "hard link" to $a. In fact they are completely equal, they are both references to the same memory location, if you unset $a, $b is still valid. The same goes with filesystem hardlinks - you can remove the original file (in fact you only "unlink" it) and the other hardlink is still valid.
