About

This project is a simple standalone calculator
The idea is: linux kernel, isolinux bootloader and a small initramfs containing only the control program /init running with PID 1

Files overview

linux.cfg - linux configuration file
isolinux.cfg - isolinux configuration file
userspace.c - control program implementing the calculator
Makefile - make script for building the distro

How to build

Make sure packages libc6-dev, musl-tools, syslinux-utils, genisoimage, qemu-system-x86 (or their alternatives) are installed
Run make
This will download linux and syslinux sources, build them and generate the image

How to use

To test the oprating system, run make test
The resulting image calculinux.iso can also be booted in VirtualBox

Customization

There is a lot of space for modifications and customizations
Run make linux_config, make linux_compile and make linux_copy to customize the kernel
To rebuild the image, run make once again

ToDo

Bare metal hardware support
Loading via univesal bootloaders like refind
EFI support
Bash-like history using readline
