Nixos Configuration
Nixos Configuration Repository
Directories
hardware-configuration
Contains the hardware configuration for each machine.
profiles
Control plane for each machine. Each profile contains the configuration and features to be enabled for each machine.
home
Contains the configuration/implementation at user level.
As much as possible, configuration should be done in here to reduce surface of attack in the system, unless requiring system-wide access like dbus or kernel modules, or root needs access to the programs.
options
Contains the options definition to toggle features in the system. Used by profiles to enable or disable features.
Options are meant to be shared between system and home. Hence, why the definitions are put in their own folder.
secrets
Contains the secrets for the system. Uses sops-nix to encrypt the secrets.
system
Contains system-wide configuration and implementation. Unless requiring system access, it's discouraged to put extended configurations here. Only parts that require system access allowed to be here.
Installation
Fresh Installation
On new machine, copy this repo, copy the hardware-configuration.nix from /etc/nixos/hardware-configuration.nix to ./hardware-configuration/<hostname>.nix.
If creating new profile and hostname, create a new <profile>.nix in ./profiles and
create a new nixosConfiguration.<hostname> option in flake.nix and
re-target the profile-path and hardware-configuration variable (specialArgs) to the new files.
Mount the root drive to /mnt, then run the following command:
nixos-install --flake /path/to/repository#<hostname>
Reinstall
If fresh from installation disk, Mount the target disk to /mnt and run the following command (Only on reinstalls):
nixos-install --flake https://github.com/tigorlazuardi/nixos#<hostname>
# There are 2 hostnames available in this repo: 'castle' or 'fort'
From Existing Installation
Same steps as Fresh Installation, but no need to mount the root drive.
Then run the following command:
sudo nixos-rebuild switch --flake /path/to/repository#<hostname>
