I have some directories with multiple hard links.  I'd like to remove one
of the hard links.  Sounds simple, right?  How do I do it?  Calling
unlink() returns EPERM (even as superuser)....  Thanks!

  For example:

	/abc/def/ghi is hard-linked to /abc/xxx/ghi (via ln -f)
        How to remove the /abc/def/ghi link?

[[ I believe that "fsck" is your only recourse.  See v7n120 for details on
a bug in "rename" that can unintentionally place you in this situation.
