Rake vs. Thor for automation scripts?

There is something important to mention here.

http://guides.rubyonrails.org/generators.html in its section 8 Application Templates.

And you could also execute system commands to satisfy your last point: Upgrade Ubuntu, install all basic packages through apt-get.
