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?
