Kernel

Hacks #88–91

When people speak of Linux, they are usually referring to an operating sys-

tem, but most Linux users know Linux is just a kernel and not a complete

OS. Of course, the kernel is the most critical piece of software on a Linux

system. Luckily for us Linux users, the open source ethos that is ingrained in

kernel development, and the hundreds of developers who peer over the code

and improve it, ensure that we have an incredibly stable and secure kernel

that forms the backbone of our operating system.

Unlike closed source operating systems in which you are given a one-size-

fits-all kernel that needs to account for a variety of hardware, the Linux ker-

nel can be customized to fit your system. This approach has both pluses and

minuses. One the one hand, this ability gives you an efficient kernel that can

perform well on a resource-poor system, or give you increased stability by

not running software that isn’t needed. On the other hand, it means you are

often faced with the task of compiling a kernel to add support for specific

hardware or to gain additional functionality.

Compiling kernels is not a difficult or scary process, but the thought of

doing so can be a bit nerve-wracking. With the range of hacks included in

this section, you will have no problem compiling the ideal kernel for your

computer.
