If I have my root fs on NFS then the same applies does it not. Your patches fail to describe the security semantics and what file rights I must have to apply each option. How do I track down a lock user, what tools are provided ? How do the new options interact with the security layer? I don't have a problem with the idea, but it needs a lot more clear description of how it works so the model can be checked and if need be things tweaked (eg needing write to denywrite etc) Alan
