Technology explained

What is systemd?

systemd is the service manager and system-initialisation framework used by many Linux distributions. This profile connects the concept to KBY's practical engineering guidance.

It manages units and their dependencies, starts services in parallel and integrates logging, timers, sockets and resource controls. Reliable administration requires understanding unit precedence, activation state and journal evidence rather than editing generated files in place.

Primary purpose
