Would the mtime of the file = not be be sufficient? I can only think of debugging purposes, but apart = from the timestamp, two kernels with the same rev. would be bitwise = identical, so I think the rev. number is more useful. Is the timestamp = not just a remnant from the CVS days? If it is useful, why not brand all binaries with a rev. number and a = timestamp? Erik= --Apple-Mail-2088-73844678--
