Linux init Process Overview
In the Linux kernel, the init process is the very first process that gets started when the system boots up. It’s essential for system initialization and for setting up everything that’s needed for the system to function properly.
🔹 How it Works:
Once the kernel has finished booting, it starts the init process (usually with PID 1). This process is the ancestor of all other processes and is responsible for starting essential system services, running startup scripts, and setting up the user environment.
🔹 Key Functions:
Start system services: It launches critical system processes and daemons (background tasks).
Handle system shutdown: If the init process ends, the system will shut down.
Control system flow: It controls the lifecycle of processes on the system.
The init process is the backbone of Linux system management, ensuring that your system runs smoothly from the start.
