在今年的CeBIT贸易展在德国汉诺威，克里斯托弗·冯·艾特森坐下来与Linux的传说克劳斯克诺佩尔讨论他的流行Knoppix的Linux发行版，以及Linux和可访问性的开源软件。
Designed to boot and run directly from a CD, DVD or USB flash drive without needing to be installed on a computer’s hard drive, Knoppix incorporates automatic hardware detection with support for a wide range of video and sound cards, USB devices and other peripherals and uses and on-the-fly decompression to run entirely in a computer’s memory. The CD version carries up to 2GB of executable software, while the single-layer DVD edition stores up to 10GB of data. The operating system can be used, for example, as a rescue system, to demonstrate Linux, as an educational CD, or installed directly to a system.
虽然许多Linux发行版，如Ubuntu或Fedora现在发布的Live CD或DVD，让用户更轻松地尝试并安装其操作系统，Knoppix的（2000年9月首次发布）是第一个Linux的实时分布找到流行中作为救援系统和在自己的权利分配。
