NixOS Configuration
A full set of configuration files managed via NixOS. This project follows the general structure of https://github.com/tiredofit/nixos-config
Running
Note on secrets management
Secrets are stored in a separate repo called nix-secrets
, which is included here as a submodule. It gets pulled into the main config via hosts/common/default.nix
. This is a poor man's secret management solution, but y'know what, it works. These "secrets" will be readable to users on the system with access to the /nix/store/
, but for single-user systems, it's fine.
Initialize the submodule with:
git submodule update --init --recursive
Applying the configuration
To apply the config for the first time (e.g. on a fresh install), run this command, replacing Shura
with the name of the host:
sudo nixos-rebuild switch --flake .#Shura
For subsequent builds, you can omit the hostname:
sudo nixos-rebuild switch --flake .
switch
replaces the running system immediately, or you can use boot
to only apply the switch during the next reboot. After applying the build at least once (or setting the hostname manually), you can omit the hostname from the command and just run nixos-rebuild build --flake .
Testing
To quickly validate the configuration, create a dry build. This builds the config without actually adding it to the system:
nixos-rebuild dry-build --flake .
To preview changes in a virtual machine, use this command to create a virtual machine image (remove the .qcow2 image after a while, otherwise data persistence might mess things up):
nixos-rebuild build-vm --flake .
Updating
flake.lock
locks the version of any packages/modules used. To update them, run nix flake update
first:
nix flake update && sudo nixos-rebuild switch --flake .
Home-manager also installs a ZSH alias, so you can just run update
or upgrade
for the same effect.
Layout
This config uses two systems: Flakes, and Home-manager.
- Flakes are the entrypoint, via
flake.nix
. This is where you include Flake modules and define Flake-specific options. - Home-manager configs live in the
users/
folders. Each user gets its ownhome-manager.nix
file too. - Modules are stored in
modules
. All of these files are imported, and you enable the ones you want to use. For example, to install Flatpak, sethost.ui.flatpak.enable = true;
.- After adding a new module, make sure to
git add
it andimport
it indefault.nix
.

Adding a host
When adding a host:
- Create its config in
hosts/hostname/<hostname>.nix
. Add itshardware-configuration.nix
here too. - Reference a profile from
profiles/
. This sets up its base configuration. - Include user accounts from
users
. - Add any host-specific options,
- Import it in
/hosts/default.nix
. - Run
nixos-rebuild
.
