Sometimes a reboot is required.
Write a script that runs "apt-get dist-upgrade" with appropriate options (things to consider might be --assume-yes/--assume-no, --trivial-only and maybe DEBIAN_FRONTEND=noninteractive. The hazard of doing an upgrade at shutdown is that you are asked a question and have walked away from the machine so it never halts). When you are happy with the script, create an initscript for it that *starts* in runlevels 0 (halt) and 6 (shutdown). Pitch it to happen sometime between X (and other user-facing services) stopping and the network going down.
