Creating a custom Linux distribution can be empowering and fulfilling for technologists, enthusiasts, and developers.
A Linux distribution is a complete operating system built on the Linux kernel, consisting of the kernel, init system, userland tools, package manager, and optional GUI.
Reasons for creating a custom distribution include learning, improving performance, branding, customization, and developing embedded applications.
To plan a custom Linux distro, define goals related to target users, hardware support, system type, and installation preferences, and choose either to build from scratch or use existing projects like Linux From Scratch.
