Hm, on second thought I think this is right. We don't want to
eternally hang upgrades on a conffile prompt, we just want to register
it. Ubuntu's upgrade tests just check for the existance of *.dpkg-dist
files [1], I suppose we can rather do this, and keep the
--force-confnew? And perhaps fail the test if we run into any of them?

Thanks,

Martin
