Versioning $HOME. Contains nix configs, dotfiles, scripts.

Config for NixOS only.

1. Clone this repo in the home folder: git clone https://github.com/f-f/home.git ~
2. Fetch everything: cd ~ && git submodule update --init --recursive --remote
3. Add the fzf module:

   mkdir -p .zprezto/contrib && cd $_
   git clone https://github.com/gpanders/fzf-prezto.git fzf
   cd fzf
   git submodule update --init

4. Write down the config for the new machine, start from the example: cd ~/nixos-config && cp local-example.nix $(hostname).nix, and integrate with what's in /etc/nixos/configuration.nix
5. Import it as a local configuration: echo "import ./$(hostname).nix" > local.nix
6. mv /etc/nixos/hardware-configuration.nix ~
7. Add channels:

sudo nix-channel --add http://nixos.org/channels/nixos-21.05 nixos
sudo nix-channel --add http://nixos.org/channels/nixos-unstable nixos-unstable
sudo nix-channel --update

Then: nixos-switch

Next:

1. Make a new ssh key for github: ssh-keygen -t ed25519 -C "$USER+github@$(hostname)" -f github, add it as deploy key here
2. Replace this repo remote from http to git: git remote set-url origin [email protected]:f-f/home.git

It's a little harder to bootstrap Nix on macOS, but it can be done. After cloning the stuff:

# In case of M1
softwareupdate --install-rosetta

# Install brew and nix
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
curl -L https://nixos.org/nix/install | sh

# Set hostname
export NEW_HOSTNAME=foo
sudo scutil --set HostName $NEW_HOSTNAME
sudo scutil --set LocalHostName $NEW_HOSTNAME
sudo scutil --set ComputerName $NEW_HOSTNAME

# At this point, edit nixos-config/flake.nix to add the new machine

# Then:
nixos-switch

# Note: it will complain at first that the nix command requires experimental features, so that will require executing the script by hand adding the right flags, but after that it's all fine
