Whether you’re a systems administrator or a home user, you need to understand how Linux internals work before you can really master Linux-how it boots, how networking works, how to customize the kernel, and even what hardware to buy.
How Linux Works contains the kind of information normally handed down from wizards-knowledge that comes from years of experience doing things the hard way. But instead of seeking the right incantation to make your system work, you can read How Linux Works to see how to administer Linux and why each particular technique works.
