### Applying the configuration
### Installing and upgrading
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:
To apply the config for the first time (e.g. on a fresh install), run these commands, replacing `Shura` with the name of the host:
```sh
nix flake update
sudo nixos-rebuild switch --flake .#Shura
```
For subsequent builds, you can omit the hostname, and/or use nh:
`nix flake update` updates the `flake.lock` file, which pins repositories to specific versions. Nix will then pull down any derivations it needs to meet the version.
> [!NOTE]
> This config installs a [Nix wrapper called nh](https://github.com/viperML/nh). Basic install/upgrade commands can be run using `nh`, but more advanced stuff should use `nixos-rebuild`.
For subsequent builds, you can omit the hostname:
```sh
nh os switch
```
or
```sh
nix flake update
sudo nixos-rebuild switch --flake .

### Upgrading
This config installs a [Nix wrapper called nh](https://github.com/viperML/nh). To use it, run:
```sh
nh os boot --update
```
You can replace `boot` with `switch`, or add `--ask` to confirm before installing.
You can also define build targets in a Nix config file. See Dimaga for an example.
