# felschr's NixOS configuration

## Installation

Clone the configuration into `/etc/nixos`.

On a new machine run:

```sh

scripts/setup-partitions

```

Then move the resulting `/mnt/etc/nixos/hardware-configuration.nix` to `./hardware/.nix`.

Update the configuration according to the script output, if necessary. Btrfs mount options likely need to be added, for example.

Copy the configuration from `/etc/nixos` to `/mnt/etc/nixos`.

Reference this hardware config in a `nixosConfigurations.` section in `flake.nix`.

Now set up a device key that will be used by agenix.

Create a new key and re-encrypt the secrets on an existing device & pull the changes.  

To create a new key run:

```sh

mkdir -p /mnt/etc/secrets/initrd

ssh-keygen -t ed25519 -N "" -f /mnt/etc/secrets/initrd/ssh_host_ed25519_key

```

You will likely need to temporarily set `age.identityPaths` for the installation to succeed:

```sh

age.identityPaths = "/etc/secrets/initrd/ssh_host_ed25519_key";

```

To install run the following command where `` matches `outputs.nixosConfigurations.` in `flake.nix`:

```sh

nixos-install --flake '/mnt/etc/nixos#'

```

After the installation finished, set a password for the user:

```

passwd 

```

## Updating

Update all flake inputs:

```sh

nix flake update

```

Update a specific flake input:

```

nix flake lock --update-input 

```

## Rebuilding the system

Rebuild the system:

```sh

sudo nixos-rebuild switch

```

Rebuild the system for a remote machine:

```sh

sudo nixos-rebuild switch --flake '/etc/nixos#' --target-host user@hostname --use-remote-sudo

```
