Debian 8—nicknamed "Jessie" after the cowgirl character in Toy Story 2 and 3—debuted last week, but it feels overdue. The release was in development within the Testing channel for quite a while, and, if you recall, Debian Linux consists of three major development branches: Stable, Testing, and Unstable. In order for a new iteration of Debian to officially go public, work must progress through each stage (starting in Unstable, ending in Stable). But it wasn't until the official feature freeze for this release in November 2014 that the contents of Testing really became what you'll actually find in Debian 8 today.
Exton|OS build 150428 is based on Ubuntu 15.04 64 bit (released April 23, 2015) and Debian Jessie (Debian 8). Exton|OS’s ISO file is a ISO-hybrid, which means that it can very easily be transferred (copied) to a USB pen drive. You can then even run Exton|OS from the USB stick and save all your system changes on the stick. I.e. you will enjoy persistence! I’ve found two scripts which make the installation to USB very simple. The scripts are quite ingenious. My tests show that they work flawlessly on USB installations of all normal Ubuntu systems. Read my INSTRUCTION how to use the scripts.
Debian is arguably the most important Linux distribution. From it springs such popular Linux distributions as Mint and Ubuntu. Outside Linux's inner circles, it's not that well known because it's purely a community operating system. There is no company behind it, as there is with Red Hat and CentOS, Fedora, and Red Hat Enterprise Linux (RHEL). Without fanfare, Debian is more than just the foundation for other better known Linux distros, it is a powerful desktop and server Linux in its own right.
