Kernels
Using RAID on Linux involves reconfiguring and modifying the Linux kernel. In general, I prefer to use monolithic kernels instead of modules, whenever possible. While kernel modules are quite useful for home desktop systems and notebooks, they aren’t the best choice for servers and production systems. The choice between the two types of kernel is ultimately up to the user. Many users prefer modules to statically compiled kernel subsystems.
In order to maintain consistency, I had to settle on specific kernels that are used in the examples found throughout this book. It’s inevitable that between the time of this writing and the release of the book, newer kernels will become available. This should not pose any problem for users working with newer kernels. This book uses kernels 2.4.18, 2.2.20, and 2.0.39, and focuses specifically on the 2.4 kernel.
