The issue is not a system-wide question, but a file-server question. As a trivial example of how to think about this problem, disk/kfscmd sync strikes closer to the way the problem should be handled than a 'sync' system call. The details of how a file server backs up and stabilizes its storage are specific to the server, and should be implemented by it. Plan 9 conventions show how to provide such an interface; the file protocol is not the place. -rob
