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
