It would break my system disk cloning scheme. Currently I mount the cloning targets, rsync the live copy, and umount the clones. That way, they will not need fsck'ing when I need them. NO big thing, though. But on a different (Linux) machine, I write dumps to a Zip drive. The medium is umounted and ejected when it's full, to be replaced by the alternate medium. So I agree a finer grained control is need. Preferably even tunable per device, allowing the Zip drive to be mounted/umounted, but no other device. I haven't looked at -CURRENT at all. How fine grained are those MACs? (Excuse me for not having the time right now to read up on them.)
