Which applications? Name them. We *really* don't want to encourage applications to make decisions only based on the mount options. For example, it could be that the application's files will have the S_DAX flag set. It would be a real shame if we are actively encourage applications to use a broken configuration mechanism which was only used as a hack while DAX was in experimental status. - Ted
