dots

This repository contains my dotfiles and a Nix flake that supports multiple hosts (machines) with a shared base and per-host configuration.

Nix Configuration

The Nix configuration is located in the nix/ directory. It uses a shared Home Manager configuration for all hosts, while allowing host-specific NixOS or package settings.

Structure

nix/flake.nix: Entry point, defines hosts and helpers.
nix/home/: Shared Home Manager configuration (packages, shell, GNOME settings).
nix/hosts/: Host-specific NixOS configurations.

Adding New Hosts

NixOS Hosts

Create a directory in nix/hosts/<hostname>/.
Add configuration.nix, hardware-configuration.nix, and packages.nix there.

Add the host to nixosConfigurations in nix/flake.nix:

limgrave = mkNixos "limgrave" [
  nix-snapd.nixosModules.default
  autofirma-nix.nixosModules.default
];

Non-NixOS Hosts (e.g., Ubuntu)

Add the host to homeConfigurations in nix/flake.nix:
```
"catalin@ubuntu" = mkHome "ubuntu" "catalin" [ ];
```
Note: mkHome takes hostname, username, and additional modules.

Building and Applying

NixOS

Run from the root of the repository:

sudo nixos-rebuild switch --flake .#hostname

Non-NixOS (Home Manager)
