I like that idea the most. Then, the image creator can
choose themselves whether (1) their image needs a tty to
function (add '-ti' to LABEL, error out if not in tty mode),
or (2) their image doesn't need a tty to function (no '-ti',
never error out), or (3), their image could make use of a
tty but does not need it ($INTERACTIVE).

Of course, you'd also need a --no-tty option or something in
the atomic cli so that you can override INTERACTIVE in cases
where you *do* have a terminal (or maybe the reverse of
that, which I think is what you suggested).
