Reproducible NixOS Builds

Install machine0

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

Define your OS as code with NixOS. Use the /create-machine skill to generate the nix code, boot a VM from it, and snapshot it so you can stamp out as many clones as you want.

# Install the /create-machine skill
machine0 skills install

# Use the skill to create a machine
claude -p "/create-machine a server that auto-starts claude code in tmux on boot"

# Code is auto-generated
ls -l claude-in-tmux/

# SSH in and you're ready
machine0 ssh claude-in-tmux
tmux attach

Or manually:

# Create a NixOS VM
machine0 new devbox --image nixos-25-11-loaded --size large

# Clone the flake, modify the config, rebuild
git clone https://github.com/fdmtl/machine0-nixos.git ./
claude -p "Add postgres to the loaded profile"
machine0 provision devbox ./flake.nix#loaded

# SSH in and start working
machine0 ssh devbox

# Create a golden master snapshot
machine0 stop devbox
machine0 images new devbox devbox-gm

# Need a clean or larger VM? Spin one up from the image
machine0 rm devbox
machine0 new devbox --image devbox-gm --size xxl

NixOS on GPUs

The nixos-25-11-nvidia image ships the NVIDIA driver stack, CUDA, and the container toolkit pre-baked — no nixos-rebuild needed. It runs on the supported NVIDIA GPU sizes: gpu-4000ada-1, gpu-6000ada-1, and gpu-h100-1 (AMD gpu-mi300x-* sizes are not supported). The SSH user is nix.

# GPU-only system images are hidden by default — list them with --all
machine0 images ls --all

# Create a GPU VM from the NVIDIA image
machine0 new ml --image nixos-25-11-nvidia --size gpu-h100-1

# SSH in and run a GPU container — drivers and CUDA are already there
machine0 ssh ml
docker run --rm --gpus all nvidia/cuda:12.4.0-base-ubuntu22.04 nvidia-smi
