It is totally up to your applications or daemons. I can guess that a simple file deletion and re-creation such like pid-files will work. As you wrote, it should be safe and surely work. But I am not sure about file-locks. In aufs, the file-lock never effect to the file on branches. If your application on nfs client locks a file without updating some data which expects the data still exist unchanged, and an application on nfs server changes the data with locking, your nfs client may lose. But it is just my guess, oen of possibilities.
