In your case, using DEBIAN_FRONTEND=noninteractive, running apt-get with -o
Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"
and redirecting stdin from /dev/null is probably appropriate.

Please note - by
default you shouldn't get prompted, and if you do it's a bug (possibly
this bug - please mark yourself as affected if you are).

Normally though, when there isn't a bug, if you change your system the
distribution doesn't want to step on your feet, so it has to prompt. It
can't have the knowledge of the customisation you've performed (only you
can know that), and doing the wrong thing may lead to a broken system.
If you don't want the prompt in automation, you can use the appropriate
options to turn it off. I don't think it makes sense to change the
default for this case; the most appropriate default is for normal
interactive use.

Hope that helps,
