I'm a newbie to the list (not unix, though :-), but anyhow...

    And none of these work any better in user space.

Well, in fact they do.

The user knows whether she treats her ZIP like a removable disk
or like a big floppy, that is, whether she should ask or refrain
from asking to read the pt.

"The User Knows"?  My experience with the vast bulk of users is that
the only thing you can count on is that they _don't_ know.  Much of
anything at all, in fact.  Depending on an luser to know how her zip disk
is configured is _much_ less reliable than some minor kernel
heuristic (translate: guesswork).
