Earlier editions of O'Reilly's Running Linux served as central guides on installing, configuring and using the OS. The third edition of this guide covers the kernel through version 2.2.1 and will prove especially useful to those with high technical aptitudes and a well-tested willingness to experiment with their computing environments. The explanation of how to rebuild the kernel--a particularly daunting task for many--deserves special praise, as do the sections on configuring network links and servers. Users will find that the informative, prose- heavy style packs maximum information into this book's pages. For example, the purpose of a Linux element is described and then the reader is shown various ways of using it, complete with explicit statements of what you type and what you get in response. Back this book up with a good command reference (Linux in a Nutshell is solid), and you'll be well on your way to Linux mastery. --David Wall, Amazon.com Topics covered: KDE and Gnome windowing systems; Samba, file, and system management; shells; windowing systems and networking; installation on Alpha, PowerPC, Motorola 680x0 and Sparc boxes.
