This is what I have:
--dir1
----file1
----file2
Then I created another directory dir2 with hard-links.
--dir2
----file1 (hard link to dir1/file1)
----file2 (hard link to dir1/file2)
Now I removed file1 and recreated a new one with the same name. How do I make the file1 in dir2 change the hard link to the new file?
