According to

Novell suggested to if you use 32bitcookie, you have to disable hardlink
as well. Has anyone tested with 32bitcookie + hardlink? 64bitcookie
causes me lots of problems and at this moment I followed Novell's
advice. However, I really need hardlink to work, anyone has tried using

Novell's document about effects of 64bitcookies is really not clear,
never mention what kind of system affected or what are the
consequences.. so I thought I was immuned but unfortunatly I am not,
many applications has problem, like pine, apache, tcsh... all of them
cannot read the contents withing a directory.
