The Debian System
—
debiansystem.info
Description
Instead of the regular user's handbook, The Debian System deals exclusively with Debian GNU/Linux and does not cover general topics, such as Linux basics, servers, or desktop environments. Rather, it details the internals of the Debian operating system and provides the reader with all the information needed to successfully administer Debian multi-user systems for years on end. The book is a must-read for the professional user of the Debian system, and an indispensable resource to the migrating Linux/Unix administrator and existing Debian user alike.
