常用示例
Reexecute
systemctl daemon-reexec
说明
systemctl daemon-reexec reexecutes the systemd manager (PID 1), replacing the running systemd binary with a new copy while preserving the current state of all units. This is used after upgrading the systemd package to apply the new binary without rebooting. Unlike `daemon-reload`, which only reloads configuration, `daemon-reexec` replaces the entire systemd process. All running services continue undisturbed during the transition.
