The Zen Kernel is a the result of a collaborative effort of kernel hackers to provide the best Linux kernel possible for every day systems. We include code that is not included in the mainline kernel in an attempt to create an all-around better kernel for desktops (although it can be compiled otherwise). This is done by including new features, supporting latest hardware, and including various code and optimizations to better suit desktops. Zen is a 100% community oriented project so, as a result, everybody can contribute to the project.

Zen is a variant of the Linux kernel that performs two major functions: (1) optimizes for desktop setups, and (2) provides a user base for project admins seeking testing for their project on various setups - these projects may or may not be seeking inclusion into the upstream Linux kernel. So, in essence, the kernel gears for desktop systems by adjusting tuning knobs and merging projects that suit this purpose in one way or another (for example, the BFS cpu scheduler is added _in addition_ to the default CFS scheduler). Additionally there are multiple things added and changed in the kernel that not everybody will benefit from (perhaps driver updates/additions and various bug fixes). The idea is to benefit Linux desktop end-users, kernel developers, and perhaps even more individuals.

Zen is a collaborative effort that includes a small group of developers but also a fairly large community that contributes much like the developers do.

	 	
It is important to the user community Mageia have available Kernel Zen, one of the most responsible kernels available!
