Overview
Both System V and systemd are init systems, used to manage processes and services on Linux systems. An init system is responsible for starting and stopping services, controlling runlevels, and providing a way to start and stop processes.
System V uses a set of init shell scripts to start and stop services. They are stored under /etc/init.d directory, and they are executed by the init process.
systemd uses unit files, which are configuration files, not executable scripts. They describe how to start and stop services. They are stored in /lib/systemd/system. They are managed by the systemd process.
