Sabayon Linux or Sabayon (formerly RR4 Linux and RR64 Linux), was an Italian Gentoo-based Linux distribution created by Fabio Erculiani and the Sabayon development team. Sabayon followed the "out of the box" philosophy, aiming to give the user a wide number of applications ready to use and a self-configured operating system. Sabayon Linux featured a rolling release cycle, its own software repository and a package management system called Entropy. Sabayon was available in both x86 and AMD64 distributions and there was support for ARMv7 in development for the BeagleBone. It was named after an Italian dessert, zabaione, which is made from eggs. Sabayon's logo was an impression of a chicken foot. In November 2020 it was announced that future Sabayon Linux versions would base on Funtoo instead of Gentoo Linux. Sabayon Linux would hence be rebranded to MocaccinoOS. Since version 4.1, Sabayon had been released in two different flavors featuring either the GNOME or KDE desktop environments, with the ultralight Fluxbox environment included as well. (In the previous versions all three environments were included in a DVD ). Since Sabayon's initial release, additional versions of Sabayon have added other X environments, including Xfce and LXDE. A CoreCD edition which featured a minimal install of Sabayon was released to allow the creation of spins of the Sabayon operating system; however, this was later discontinued and replaced by CoreCDX (fluxbox window manager) and Spinbase (no X environment) first and by "Sabayon Minimal" later. A ServerBase edition was released which featured a server-optimized kernel and a small footprint, but this was later discontinued and integrated into the "Sabayon Minimal". Daily build images were available to Sabayon testers, but were released weekly to the public on the system mirrors containing stable releases. Official releases were simply DAILY versions which had received deeper testing. The adoption of Molecule led the team to change the naming system for releases.
