A Simple collection of scripts to build a super small "distro" that only runs the kernel as a starting point

This is stable, but not production ready in any way.
Exiting the shell will kernel panic. The build process is not really that portable either and will litter(mess with files outside of build dir) a system on building. And I'm aware that the "project" structure is messy, But... it boots! This was hobby thing mostly.

Not Linux From Scratch

This is a fun hobby project where I have made some scripts for quick and easy creation and booting of a linux kernel and inital file system. It's super small and fast, infact the gif right above competes with both file size and time to complete/boot! No, but seriously it's super fast and small. Beware though, there is not init system (systemd/openRC/runit). No real folder structure (like /proc /var). But it is amazing at running only one thing and could be used as a base for a new distro or a gaming console if you throw in some SDL2 in it. As of writing this, I have no real plan other then exploring how this all works under the hood. I'll strip the kernel some more and maybe move this into a raspberry pi console...

Building

In Bootstarp System (ArchWSL):
git clone https://github.com/itsmagu/Not-LFS /work-files/ In order:

sh ./initalize
./fetchSources # Make sure that Busybox compiles as static (make menuconfig)
./buildKernel
./buildInitramfs
./buildCpio
./copyToBootFile
./pushToVM

TODO: move to make (I am just lazy, but lot of files are messy)

Running

I run with Qemu on a Windows host:
qemu-system-x86_64.exe C:\VM\boot -nographic -serial mon:stdio -m 1G

Prerequisites

I use ArchLinux as the bootstrap system in WSL on windows (Google the repo for ArchWSL)
The Scripts expect a "C:/VM/" dir on the host windows system for qemu to boot and a "root/source" in the WSL system. If you understand how this all works you can edit and change the folders or even from ArchWSL and the Windows host setup.
