I think apt-get upgrade could be particularly devestating if combined with red-pill mode.

I don't know why the NIT is set up like this.. if I do a test-upgrade (apt-get upgrade -s, which doesn't install anything) I see a lot of upgrades that certainly aren't visible inside application manager. This way of doing it isn't inherent in the Debian package management system, so I don't know why it's like this in the NIT.
