To say clear Systemd, you have to start with the Linux operating system started speaking. The startup of the Linux operating system starts with the BIOS, then the boot Loader loads into the kernel and initializes the kernel. The final step in kernel initialization is to start the init process. This process is the first process of the system, PID 1, also known as the super process, called the root process. It is responsible for generating all other use
