Guys, what are you all talking about?
You can't "hardlink" directories and you can't "hardlink" across
file system boundaries. What you call "hardlink" is the process of
creating a directory entry referencing an inode already referenced
by some other directory entry within the same filesystem.

Wrong. It's about directories, not about inodes.
$ mkdir foo bar
$ echo gaga > foo/gaga
$ ln {foo,bar}/gaga
$ cp -p /bin/sh foo
$ sudo chroot foo /sh -c ':> gaga'
$ ls -l bar
