# FelschR's NixOS configuration
# felschr's NixOS configuration
## Installation on new machine
To setup a new machine run the following command after completing partitioning and mounting:
## Installation
Clone the configuraiton into `etc/nixos`.
On a new machine run:
```sh
nixos-generate-config --root /mnt
```
./install.sh <NIX_CONFIG>
Then move the resulting `/etc/nixos/hardware-configuration.nix` to `./hardware/<config>.nix` and adjust it and the `flake.nix` accodringly.
Make sure everything was properly recognised. Btrfs mount options might be missing, for example.
To install run the following command where `<config>` matches `outputs.nixosConfigurations.<config>` in `flake.nix`:
```sh
nixos-install --flake /etc/nixos#<config>
```
## Updating
Update all or specific locked flake inputs:
```sh
nix flake update
nix flake update --update-input <input>
```
## Rebuilding the system
Rebuild the system:
```sh
sudo nixos-rebuild switch
```
Update flake.lock and rebuild the system:
```sh
nix flake update && sudo nixos-rebuild switch
```
This runs `nixos-generate-config`, symlinks the passed configuration to `/etc/nixos/configuration.nix`, sets up required nix channels and then runs `nixos-install`.
