Although there hasn’t been any time to test this rather radical approach to the Linux kernel , the zen of kernel development is worth reporting about. After my initial fore’s into kernel evolution, here and here, I stumbled across ZenKernel.
“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 almost always more up to date than your distribution’s default kernel. Zen is split up into two trees, these are stable (zen-stable.git) and unstable (zen.git). The stable tree follows Linux releases while the unstable tree follows the Linux git tree (linux-2.6.git).”
You have a choice between doing it the ZenKernel way or cheating and using the buildZen script. Remember, using scripts to build kernel’s is strictly speaking, cheating. Not recommended if you want to understand what is going on and/or contribute to development. There is also some good advice and information on the Ubuntu Wiki
