Systemd is a relatively recent approach for managing OS and system services, their startup/shutdown and logging in modern Linux distros.
Notable Changes Brought By systemd
- There are no more /etc/init.d scripts for startup/shutdown services
- Logging isn't done directly into files, but instead goes into centralised systemd journaling system
- Service management scripts are operated by systemctl command
- Logs for the OS and individual services are accessed by journalctl command
