Yoper Linux—Your Operating System—is a Linux distribution for PCs with i686 (Pentium Pro) or higher processor types. It can be used for both desktop and server use and uses hardware recognition tools known from Knoppix.

The defining feature of the distribution is a set of custom optimizations intended to make it the “fastest out-of-the-box distribution.” The project was originally founded by Andreas Girardet as an one man distro and has moved on to be maintained by a group of people around Tobias, its current lead developer. The distribution is scratch-built as opposed to modifying one of the more popular distributions to create a new distribution. There is no denying of influences though. So there are recognizable elements from other Linux distributions ranging from Archlinux, Ark , Gentoo and Fedora.
