1 About systemd

systemd is the system initialization and service manager in Oracle Linux. The systemd daemon is the first process that starts after a system boots and is the final process that's running when the system shuts down. systemd controls the final stages of booting and prepares the system for use. It also speeds up booting by loading services concurrently.

Tip:
