On Sat, Oct 24, 2009 at 10:36:11PM +0400, Dan Yefimov scribbled thusly:

Thus Debian kernel team should be blamed for that misbehaviour. Don't 
worry, hardlinks behave just the same way, as you describe. Use authentic 
Linux kernels, if you dislike that.


Shall we blame Red Hat too? Just tested on 2.6.18-164.2.1.el5,
although with a single user since I don't actually run RHEL on
any of my own computers.
