This problem is actually mine. This is not homework, but some extra work i'm doing. I asked Somil Asthana to post for me on the bsd newsgroups he knows. what he posted was what i asked him to post. After working the last 3 nights as my vacations have started, I figured out that the bug lay in the iovectors which was overlooked by misleading printf statements.......So its not necsasry for anyone to respond but any discussion on nullfs and its idiosyncracies would be appreciated. tony On Mon, 23 Dec 2002, Erez Zadok wrote: > In message , Tony Gogoi writes: > > Hi everyone, > > > > I was referred by someone to post my question here.
