This repository contains configuration files for building a custom NixOS ISO. The ISO is based on the nixos-unstable repository and includes the latest Zen kernel (6.8+) with support for the latest filesystems, including bcachefs, btrfs, ext4.

Two types of ISO can be built:-

• Graphical
• Minimal

See different instructions below.

This guide assumes that you have nix setup in your system or/and are using NixOS.

To build the custom NixOS ISO, follow these steps:

1. Clone this repository to your local machine.
2. Navigate to the repository directory.
3. Run the build command.

git clone https://github.com/JohnRTitor/nix-iso.git
cd nix-iso

• For building full graphical ISO

nix build .#nixosConfigurations.nixos-iso.config.system.build.isoImage

• For building minimal ISO

nix build .#nixosConfigurations.nixos-minimal.config.system.build.isoImage

Ensure that flakes and nix-command are enabled on the host system before building the ISO.

The resulting ISO image can be found in the ./result/iso/ directory.

A week ago, I had to make an ISO image to support bcachefs filesystem because official ISO releases back then did not have the latest kernel. I quickly looked up the docs, put together a shaky configuration to build it for myself. Have been using the system with Bcachefs since and it is chill af. Figured some people might be in a similar situation, so here we are...

I also provide minimal ISO builds via this repo (check Releases). May be outdated though by the time you are reading this, ping me up by creating an issue, I'll provide an updated release ASAP.
