  24       <div class="date">30th August 2010</div>
  25       <div class="body"><p>Just got an email from Tobias Gruetzmacher as a followup on my
  26 <a href="http://people.skolelinux.org/pere/blog/Broken_umask_handling_with_sshfs.html">previous
  27 post about sshfs</a>.  He reported another problem with sshfs.  It
  28 fail to handle hard links properly.  A simple way to spot this is to
  29 look at the . and .. entries in the directory tree.  These should have
  30 a link count >1, but on sshfs the count is 1.  I just tested to see
  31 what happen when trying to hardlink, and this fail as well:</p>
  32
  33 <pre>
  34 % ln foo bar
  35 ln: creating hard link `bar' => `foo': Function not implemented
  36 %
  37 </pre>
  38
  39 <p>I have not yet found time to implement a test for this in my file
  40 system test code, but believe having working hard links is useful to
  41 avoid surprised unix programs.  Not as useful as working file locking
  42 and symlinks, which are required to get a working desktop, but useful
  43 nevertheless. :)</p>
  44
  45 <p>The latest version of the file system test code is available via
  46 git from
