I issue an imperative command to apt-get, and it tries to execute it.
It has no knowledge of why I want foo bar and baz installed, nor can it decide if these 3 programs make sense for what I am trying to do, or if there is a better way to do it (maybe there is a package "bazinga", that can replace the foo-bar-baz stack?).
A goal-aware package manager would look like this:
super-apt "i need the system ready to function as a webserver, with a high availability database and backup capabilities"
