My personal Nix configuration flake.

Nix configuration flake for my personal machines (macOS and NixOS).

💡Inspired by buntec's setup

Fresh NixOS install

After installing NixOS from a USB drive, follow these steps:

1. Clone this repo and cd into it.

2. Copy /etc/nixos/hardware-configuration.nix into ./system (OK to overwrite existing dummy file).

3. Finally, to build and activate in one step using the apps provided by the flake

nix run .#rebuild-nixos # system configuration
nix run .#hm-switch-nixos # dotfiles and home configuration

Fresh macOS install

(Heavily inspired by this gist)

To bootstrap a fresh macOS install, follow these steps:

1. Install Homebrew (only needed for managing GUI apps via casks)

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Nix:

curl -L https://nixos.org/nix/install | sh

3. Enable flakes

mkdir -p ~/.config/nix
cat <<EOF > ~/.config/nix/nix.conf
experimental-features = nix-command flakes
EOF

4. To work around this issue

sudo mv /etc/nix/nix.conf /etc/nix/.nix-darwin.bkp.nix.conf

5. Clone this repo, cd into it, then build and activate with the following commands:

nix run .#rebuild-macbook-air-m2 # system configuration
nix run .#hm-switch-macbook-air-m2 # dotfiles and home configuration

Fresh WSL install

1. Install WSL from PowerShell:

wsl --install

2. Set the hostname to wsl by editing /etc/wsl.conf inside the WSL distro:

[network]
hostname=wsl
generateHosts=false

After editing /etc/wsl.conf, run wsl --shutdown from PowerShell and restart WSL for the changes to take effect.

3. Install Nix:

curl -L https://nixos.org/nix/install | sh

4. Enable flakes:

mkdir -p ~/.config/nix
cat <<EOF > ~/.config/nix/nix.conf
experimental-features = nix-command flakes
EOF

5. Clone this repo and apply the configuration:

nix run .#hm-switch-wsl

Fresh Windows install (via Multipass)

1. Clone this repo, then launch a VM (cloud-init installs Nix automatically):

multipass launch -n nix -c 2 -m 8G -d 64G --cloud-init extras\multipass-cloud-init-x86.yml

2. Wait for cloud-init to finish, shell in, and switch to the xxx user:

multipass exec nix -- sudo su - xxx

3. Clone this repo inside the VM and apply the configuration:

nix run .#hm-multipass-guest-x86

Migrating an existing macOS install to Nix

1. Uninstall Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

2. Delete everything under ~/.config and any other "dot files" in your home directory.

3. Delete all applications that are listed as Homebrew casks in ./system/configuration-darwin.nix

4. Follow the steps for a fresh macOS install.
