I am not positive on rename, but I believe that it will actually be atomic on NFS partitions as long as the data does not cross file-system boundaries. If you know of solid documentation on this one way or another, that would be good.

As for locking, Linux dropped the use of fcntl/lockf for flock a while ago due to some nasty recurring bugs. So flock does not work over NFS for Linux any more. Also fcntl did not when I tried it work totally smoothly. But I did not tinker much, that was a while ago, and I know that in the last few 2.2 releases (and of course in the new 2.4 series) NFS was improved greatly.
