Initially, I created this project four years ago as a way to learn Python. At that time, it wasn't named ProcyonCLS or DonutCLS; I simply referred to it as Simple CLI. As I continued to learn, I renamed it Py-DOS, even though it wasn't an actual operating system. Eventually, I stopped working on it, thinking it was pointless—after all, who uses a CLI application that does nothing in the age of GUIs? However, last month, after completing my final exam for the third semester of my BCA degree, I revisited the project out of boredom. This time, instead of a single Python file, I developed a bootloader, kernel, and shell to demonstrate to some friends the basics of how a real operating system functions. It wasn't a true OS, but it served as a useful illustration. Later, I decided to upload it to my GitHub, regardless of whether it would be used or not. The first GitHub release of ProcyonCLS was version 0.5, back when the release name '2025' had not been established, and it was simply known as "ProcyonCLS Codename Munnar."
Greetings, and welcome to my blog. Today, I will discuss how to create a simple Linux distribution using BusyBox . This can be done on any system, whether it is Windows, macOS, or Linux. For Windows, you need WSL, a Docker (Ubuntu) container, or a VM with a Linux distribution installed (Ubuntu or its derivatives are recommended). First, install the prerequisites: Note : If you are using a container, ensure you run it in privileged mode. Bash sudo apt install bc cpio bison libssl-dev libncurses-dev libelf-dev bzip2 make sudo apt install automake autoconf git syslinux dosfstools xz-utils build-essential gcc wget Once you have these dependencies installed, start by creating a directory named distro : Bash sudo mkdir /distro cd /distro After creating and changing the directory, obtain the Linux Kernel, either from git or wget: Note : If you use git, you might clone the beta or release candidate version of the kernel. Bash sudo git clone --depth 1 https://github.com/torvalds/linux OR...
