machine0-nixos

This repository contains the profiles that are used to build the machine0 NixOS system images. This is a great place to start if you want to customize your NixOS VM.

Usage

# install the machine0 CLI
curl -LsSf https://machine0.io/install.sh | sh

# create a NixOS VM
machine0 new nixos --image nixos-25-11-loaded --size medium

# clone the repo, customize and rebuild
git clone https://github.com/fdmtl/machine0-nixos.git && cd machine0-nixos
claude -p "make any change to the loaded profile you'd like"
machine0 provision nixos ./flake.nix#loaded

# or, rebuild from within the VM
machine0 ssh nixos
git clone https://github.com/fdmtl/machine0-nixos.git && cd machine0-nixos
./rebuild.sh

Note: We strongly recommend --size medium or larger. Nix builds are CPU and memory intensive — small instances work but take forever.

Profiles

Image Name	Profile	Description
nixos-25-11	#base	Minimal NixOS installation
nixos-25-11-loaded	#loaded	Modern agents (Claude, Codex...) and dev tools (e.g. Docker, Node, Python...).
nixos-25-11-openclaw	#openclaw	Loaded + OpenClaw.
nixos-25-11-hermes	#hermes	Loaded + Hermes Agent.

The (profile → image) mapping is canonical in manifest.json and consumed by the build/test scripts.
