NixOS Configuration Files

A set of NixOS configuration files and build helpers.

• NixOS build files named like <hostname>-configuration.nix, included files are named like _*.nix.
• extra/post-install-config.sh is a distribution agnostic shell script that installs configuration settings that are not managed by Nix (dotfiles and GNOME desktop shortcuts).

TODO

• Move from channels to flake-based configurations.

Usage

1. If you haven't already done so, you will need to install and log in to NixOS on the target machine.

2. Download this repo.

   cd ~
   git clone https://github.com/srackham/nixos-configurations.git

3. Optionally edit configuration files.

4. Rebuild NixOS using the mknixos alias:

   alias mknixos="sudo nixos-rebuild -I nixos-config=$HOME/nixos-configurations/$HOST-configuration.nix"
   
   mknixos switch  # Run `nixos-rebuild switch`.

Host Configurations

• nixos1: GNOME desktop VirtualBox guest.
• rpi1: Raspberry Pi 4 NAS server (CUPS, NFS, SMB).

Nix modules imported by host configuration files:

• _rp4.nix: Raspberry Pi 4 specific.
• _server.nix: services, packages and users.
