Under systemd a daemon does not fork or write pid files. It stays in the foreground, tells systemd when it is ready and exits cleanly on SIGTERM.

Under systemd a daemon does not fork or write pid files. It stays in the foreground, tells systemd when it is ready and exits cleanly on SIGTERM.

Run a Rust service under systemd properly: a unit file with hardening, sd_notify readiness, socket activation for zero-downtime restarts, the watchdog heartbeat and journald logging.

Run a Rust binary on a Linux server under systemd: a locked down unit file, a dedicated user, environment files, restart policy, logs through journald and a simple release procedure.
