In the world of Live-Linux CDs Knoppix stands alone. For many, Knoppix was the first Linux distribution all packaged and able to run on a Live-CD, though today there are myriad of other options available.
“Version 7.3.0 of Knoppix is based on the usual picks from Debian stable (wheezy) and newer Desktop packages from Debian/testing and Debian/unstable (jessie),” the Knoppix 7.3 release notes state. ” It uses kernel 3.13.0 and xorg 7.7 (core 1.15.0) for supporting current computer hardware.”
