POSIX-compliance of link(2)


-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

According to POSIX, creating a hardlink to a symlink is supposed to be
impossible, because link(2) is supposed to resolve symlinks before
performing the actual link.  See
http://www.opengroup.org/austin/mailarchives/ag/msg08153.html.

$ touch a
$ ln -s a b
$ link b c      # Bug: c should be a hard link to a, not b
$ ls -l a b c
- -rw-r--r--  1 eblake None 0 Mar 15 19:04 a
lrwxrwxrwx  2 eblake None 1 Mar 15 19:04 b -> a
lrwxrwxrwx  2 eblake None 1 Mar 15 19:04 c -> a
