The Design and Implementation of the Freebsd Operating System - 9780321968975

For many years, The Design and Implementation of the FreeBSD Operating System has been recognized as the most complete, up-to-date, and authoritative technical guide to FreeBSD's internal structure. Now, this definitive guide has been extensively updated to reflect all major FreeBSD improvements between Versions 5 and Versions 11.

Approximately one-third of the content in this edition is completely new, and another one-third has been extensively rewritten. The authors fully cover every FreeBSD improvement today's sysadmins, application and system programmers, and support professionals need to know about.

Three leading FreeBSD experts begin by providing a concise overview of FreeBSD's current design and implementation. Next, while explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant systems facility. Readers can use this book as both a working reference and an in-depth study of a leading contemporary, portable, open source operating system.

The many new topics covered in this edition include:

• Lightweight virtualization, enabling organizations to support hundreds of instances on one system
• Fine-grained authority delegation, providing far more administrative flexibility
• NFS V4 and OpenSolaris ZFS support
• Improved volume management and new journaled soft updates
• DTrace fine-grained process debugging/profiling
• Major improvements to networking, wireless, and USB support
• And much more
