Coding a linux-based OS
- Building a Linux-based operating system involves a journey of configuration and customization with a lot of groundwork already laid.
- The Linux kernel is the heart of any Linux-based OS that manages system resources, handles memory management, and oversees process scheduling. It provides flexibility, stability, and immense community support with modular design.
- The bootloader is responsible for getting the system up and running and most people use GRUB (Grand Unified Bootloader) for Linux-based systems.
- System initialization comes next and is where init systems like SysVinit, runit comes into play. Systemd is the standard init system in Linux that manages processes, services, logging, and more.
- Hardware management with the Linux kernel already includes support for a vast range of hardware devices making managing hardware much smoother compared to writing device drivers from scratch.
- Choosing the right file system like ext4, Btrfs, and XFS depends on the user's needs for a Linux-based system.
- Adding a desktop environment like GNOME or KDE provided with display servers like X11 or Wayland for a graphical user interface is essential for desktop OS.
- The shell is where users interact with the system for running commands and managing files on the Linux system.
- The process of building a Linux-based OS is to find the balance between customizing for specific use cases and leveraging the immense power of the Linux ecosystem.
- Configuring, optimizing, and integrating these components are needed to create a seamlessly user-friendly operating system after the groundwork is laid for Linux-based OS.
