"Sabayon is to Gentoo what Ubuntu is to Debian--it's a Gentoo
fork, and a very good one at that. If you're having issues with
Ubuntu, you have past experience with Gentoo, or you'd rather get
your feet wet with Gentoo then Debian, give Sabayon a shot.
"There are two versions of Sabayon--the full desktop version,
and a mini version, which is ideal for older computer, low-capacity
netbooks, or just to reduce the size of you install.
"Sabayon is released as a LiveCD and can be easily installed
from that. During installation, you can choose to install the
default KDE interface, or instead add Gnome or XFCE. The rest of
the installation is identical to Ubuntu, and involves selecting
simple settings."
