My experience with etch's aptitude is that it would never find a solution
(not even if you give him several minutes) to the problem posed by a
complex dist-upgrade while apt-get would correctly manage it even though
it requires removing some packages which disappeared and so on.
In short, I would mention that one can use "apt-get dist-upgrade" as fallback. And
in the long term, I would really like that apt-get / aptitude collaborate
more closely and use a common database of "auto-installed packages".
Because it's the main point that justifies the use of aptitude when you're
not interested in the ncurses gui.
