Dario, This is all just what I think :) Anyone feel free to tell me I'm wrong :)
If you want some advice, Installing everything would create a horrendously unstable debian system, in my opinion. There are just some packages that_don't_work_together, ie if you install them, that will create conflicts that will cause your system to stop functioning at a basic level. That's why we have package dependencies - so we can tell what should be installed at the same time as another package - and what shouldn't. For example, if I remember correctly, if you install debconf and debconf-tiny, they conflict with each other. There's really no point to doing it! You can't use them both at the same time. In my experience, the debian package management system is intelligent enough to tell you this, whereas the redhat one isn't. Renai
