Symphony OS
Description
Symphony OS, or Symphony Linux, is a LiveCD Linux distribution, created by Ryan Quinn and Jason Spisak. It is under active development, and is beta software.
When it started, Symphony OS was based on Knoppix. Since its May 2006 release it is no longer based on Knoppix, but rather on Debian unstable, and features a functional hard drive installer. The forthcoming release, Symphony OS 2007 Preview, will be based on Ubuntu 7.04.
The primary difference between Symphony OS and other distributions is the addition of the Mezzo desktop environment. This environment, like other aspects of Symphony, was designed with an eye towards extreme simplicity and usability. Symphony also includes its own Mozilla-driven application environment, called Orchestra.
Symphony OS uses a custom packaging system utilizing the *.sym package format; through a simple GUI interface a user may install any application in the Symphony library without dealing with "dependency hell". Because Symphony is Debian-based, it also supports the Debian package format.
