By honing in on your particular focus areas, this book delivers precise guidance to efficiently develop and troubleshoot device drivers within FreeBSD’s kernel environment.

When Michael W Lucas first delved into the intricate world of FreeBSD's specialty filesystems, he recognized a gap in clear, focused guidance on these essential components. Drawing from his extensive experience as a prolific technical author, Lucas walks you through managing a diverse array of filesystems beyond the basics, including devfs, union mounts, null mounts, and networked storage solutions like iSCSI and HAST. You’ll gain practical understanding of how these filesystems support everything from application servers to jails, with chapters dedicated to specific systems such as the POSIX message queue and Solaris-compatible automounter. This book is tailored for system administrators aiming to deepen their FreeBSD expertise, especially those who need to solve nuanced storage challenges.

When Samuel J. Leffler first uncovered the intricate mechanics behind the 4.3BSD Unix system, he set out to demystify its complex internal operations for engineers and enthusiasts alike. This book walks you through the system’s core data structures, algorithms, and design principles, providing detailed solutions to exercises that deepen your understanding of the BSD operating system's architecture. You’ll gain hands-on insights into how key system facilities are implemented, which benefits software developers, system programmers, and anyone involved in operating system design. The book’s concise yet focused approach makes it ideal for readers aiming to master BSD’s underpinnings without wading through extraneous theory.

What if everything you knew about BSD operating systems was incomplete? Dr. Marshall Kirk McKusick and his co-authors challenge conventional wisdom by diving deep into the architecture of 4.4BSD, explaining major changes in process and memory management, and introducing the new extensible filesystem interface. You’ll gain detailed insights into networking, interprocess communication, and filesystem design that are crucial for systems programmers and application developers alike. Chapters like the one on the network filesystem offer a granular look at how BSD’s internals function, making it essential if you want to understand or extend this influential OS.
