The ISO files are already available here - https://github.com/ArseLinuxOS-Development/ArseLinuxOS-ISO/releases
But if you wish to help out with development it’s always handy to know how to build an ISO yourself.
This ISO is based on a modified Arch-ISO to provide Installation Environment for ArseLinuxOS. As you can imagine, this project is for fun and isn’t meant to be used for anything serious, or rather, anything at all.
Building
git clone https://github.com/LiamAEdwards/ArseLinuxOS-ISO.git && cd ArseLinuxOS-ISO
mkarchiso -v -w /archiso-tmp -o ../ .
With Docker
docker build -t arselinux-build . --no-cache
docker run --privileged -it arselinux-build:latest /bin/bash
Once completed you will have an ISO image to test/boot.
