Tools, scripts, and configurations for my machines.

## Steps for a new Darwin machine

Start by installing nix, using [nix-installer](https://github.com/DeterminateSystems/nix-installer) from [DeterminateSystems](https://determinate.systems).

```sh
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install
```

Next, we need to install [homebrew](https://brew.sh):
```sh
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
```

Finally, we need a [GitHub personal access token](https://github.com/settings/personal-access-tokens). Create one with an expiration time, and renew it when ever it's about to expire (we will get an email about this). The token needs to be stored in `~/.config/nix/nix.conf`:

```
access-tokens = github.com=****
```

Now you can build the configuration (remember, the host name is in lower case) :
```sh
nix run nix-darwin -- switch --flake .
```

Finally, switch the default shell via `chsh`, and set it to `/run/current-system/sw/bin/fish`.

Best to reboot to complete the installation.

## Steps for a new droplet on DigitalOcean

Start by creating a droplet using Debian. Create a new host configuration.

Once the droplet is provisioned, we can use `nixos-anywhere` to convert the droplet to a NixOS installation.
```sh
nix run github:nix-community/nixos-anywhere -- --flake .#<host> --target-host root@<IP>
```

Once the host reboots, check that it's converted to NixOS by running `uname -a`.
