System Administration with Systemd

This opening volume launches a new series on the fundamentals of running the Raspberry Pi OS. It is written for beginners and gathers the essential system administration tasks a newcomer needs, presented in an approachable way. Its central theme is systemd, which the book treats as the mechanism by which a modern 21st-century Linux system such as this one lets its kernel operate efficiently. Systemd supports three basic pillars of computing: concurrent execution, virtualization, and secure persistence.

Learning is reinforced by exercises placed throughout the chapters. Solutions and example code are provided on an accompanying GitHub site. Numerous practical examples and projects let readers apply the material to real systems.

The book is intended for students and working practitioners who want to get more out of the Raspberry Pi OS. It can also serve as a supplement in formal courses, extending a learner's basic knowledge of Linux operating systems.
