Sabayon Linux or Sabayon (formerly RR4 Linux and RR64 Linux), is a Gentoo-based Italian Linux distribution created by Fabio Erculiani and the Sabayon development team. Sabayon follows 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 features a rolling release cycle, its own software repository and a package management system called Entropy. Sabayon is available in both x86 and AMD64 distributions and there is support for ARMv7 in development for the BeagleBone.[
It is named after an Italian dessert, zabaione, which is made from eggs. Sabayon's logo is an impression of a chicken foot.
