Code review comment for lp:~bjornt/landscape-client/apt-upgrade-all-packages

I believe we don't want dist-upgrade, as it can have quite disruptive effects like removing packages, or replacing postgres-8 with postgres-9 (in principle).

Also I didn't look at the code very in depth, but will this have really the same behavior as before? The important thing is to go back to the server if there are package changes that haven't been explicitly requested by the server (with install/remove messages) and that are not allowed by the auto-apply policy in effect.
