The people who write darcs (an incredibly powerful/flexible version control system) are looking into making sure that it works properly on AFS, and were looking for an authoritative, official statement of exactly how AFS file semantics differ from UNIX semantics:
http://bugs.darcs.net/issue117 Specifically, can anybody comment on these points? 1. If two processes on different clients both attempt to open(O_CREAT|O_EXCL), does AFS guarantee that no more than one of them will succeed? 2. If two processes both attempt to rename() the same [source] file, does AFS guarantee that exactly one of them succeeds? 3. If client "A" makes two inode-level changes (creat, remove, rename, etc), is it ever possible for client "B" to see the second change before the first one?
