But I know what I'm doing: I don't just need a running system, I want to build my own system like I do with my Gentoo. I just want to speed up with some steps, like installing the server X. But I need to build my own copy of kde from svn and some others thinks.
So, I think I can install the basic system with entropy, then "forget" it (until there are updates for the installed packages) and build from sources the DE and the apps.
Actually Spiros 2 of the links provided (in my second paragraph) do guide you towards building a stable working system with the base core CD and using portage combined with equo/entropy to build a safe-sane system without package breakage.
This is what I did. I was having a hell of a time with dependency issues with my old Gentoo set-up upgrading to KDE4. So I decided to rebuild my system from scratch. Since my divorce last year, I don't have a broadband internet connection and rely on going to the library or local Starbucks which have wifi connections. What I did was burn a copy of the Sabayon-KDE DVD and core CD. Then I installed the core CD onto my laptop. Then I used the DVD to edit any files I needed and to chroot into the core system on my laptop. The DVD allowed me to get internet and download anything I needed.
My plan was to recompile my system with my own use flags and compiler options. First, I followed exactly what was said in the second link I listed about using the core CD, from the Sabayon Wiki, to get up and running. After doing this I made the changes I wanted to the various configuration files, then I would just "emerge --fetchonly" what I needed, to get onto my laptop. I utilized the bandwidth I could get from these public places. Then I compiled at home. Now my system is up and running exactly how I want. It's now a ~86 Gentoo KDE system with a Sabayon overlay for portage. Doing it this way saved me many hours of compiling and setting-up for the initial system and allowed me to keep using my machine via the complete system on the DVD while I was constructing my setup on my laptop.
I hope this helps,
