LinuxBSDos.com published a review on Sabayon 7 GNOME 3
Sabayon is a Linux distribution described by its developers as “… a bleeding edge operating system that is both stable and reliable.” It is based on Gentoo, a source-based (Linux) distribution. The latest edition, Sabayon 7, was released just last week (October 10 2011 to be exact). Sabayon has support for all the known free desktop environments, but this release, as is customary, includes 32- and 64-bit installation images for GNOME 3, the K Desktop Environment, and Xfce only.Sabayon 7 GNOME 3 review
This review is based on test installations of the 32-bit edition of the GNOME 3 edition, which comes as a DVD-sized, installable Live image. The boot menu, which has more options than any other distribution that I am aware of, is shown below. In spite of the number of available boot options, it could still use one more, which I have added in red.
