Install Nix

curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | \
  sh -s -- install --no-confirm --extra-conf "trusted-users = root $(whoami)"

Build Machine

It is probably best to run this command:

nix --accept-flake-config run github:juspay/omnix -- init github:juspay/nixos-unified-template -o $HOME/.config/nixconfig

Answer the prompts and then you will have a working config. To make it more useful (to myself) copy the modules directory and wire it up in each configuration.

If you are just moving configs between machines follow the steps below:

cp nix.conf $HOME/nix/nix.conf
cp nixconfig $HOME/.config/nixconfig
cd $HOME/.config/nixconfig

# One-time activation
nix --extra-experimental-features "nix-command flakes" run

To update:

nix flake update && nix run [. $USER@ ] # add the ' .$USER@' on non-NixOS Linux

To update nix:

nix upgrade-nix --nix-store-paths-url https://install.determinate.systems/nix-upgrade/stable/universal

Rebuild System

nix --extra-experimental-features "nix-command flakes" run nix-darwin#darwin-uninstaller
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- uninstall

sudo mv /etc/nix/nix.conf /etc/nix/nix.conf.before-nix-darwin
sudo mv /etc/bashrc /etc/bashrc.before-nix-darwin
sudo mv /etc/zshrc /etc/zshrc.before-nix-darwin
