# Auxolotl System Template
A (nearly) complete and ready-to-run NixOS template.
A ready-to-run NixOS template with sane defaults.
## Getting Started
1. Install a fresh copy of NixOS and boot into your new system.
2. Run [command] to generate your system's `hardware-configuration.nix` file.
3. Copy `hardware-configuration.nix` into the `hosts/myHost` folder.
4. Edit the `hosts/myHost/configuration.nix` file to suit your needs. This file is fully documented with all of the different options available in this template.
5. Run `nixos-rebuild boot --flake .` and restart.
2. Download, copy, or clone this repository onto your new system.
3. Run `nixos-generate-config --show-hardware-config` to generate your system's `hardware-configuration.nix` file. Copy this file into the `host` folder, overwriting the existing file.
4. Edit `flake.nix` and set the value of `hostName` to the host name you want to use for this system.
4. Edit the `host/configuration.nix` file to suit your needs. This file contains all of the available options and is fully documented.
5. Run `nixos-rebuild boot --flake .#<your hostname>` and restart.
6. Enjoy your new NixOS system!
## Additional options
This section is for options that require additional information or setup.
### Hardware-specific options
NixOS-Hardware is a community library of NixOS modules to work around quirks with specific kinds of hardware, especially laptops and SBCs like Raspberry Pis. If you know your system's model, you can see if it's available in [NixOS-Hardware by checking the project's flake.nix](https://github.com/NixOS/nixos-hardware/blob/master/flake.nix). If so, add its module to your host's `flake.nix` like so:
```nix
modules = [
...
nixos-hardware.nixosModules.framework-13th-gen-intel
...
]
```
### Secure Boot support
This configuration supports [Secure Boot](https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface/Secure_Boot) systems, but with some additional setup required. Secure Boot is a UEFI standard meant to prevent the pre-boot process by requiring boot images to be signed by a trusted authority. The goal is to prevent tampering, e.g. by a malicious third-party replacing your kernel image with a compromised image. In NixOS, Secure Boot support is provided by the [Lanzaboote](https://github.com/nix-community/lanzaboote) project.
To enable Secure Boot support:
1. Install NixOS using the default `systemd-boot` bootloader, and with Secure Boot disabled via UEFI. To confirm this, run `bootctl status` and look for output similar to the following:
```sh
$ bootctl status
System:
Firmware: UEFI 2.70 (Lenovo 0.4720)
Secure Boot: disabled (disabled)
TPM2 Support: yes
Boot into FW: supported
Current Boot Loader:
Product: systemd-boot 251.7
...
```
2. Generate a set of Secure Boot keys by running the following command: `sudo sbctl create-keys`. This creates a set of keys in `/etc/secureboot`.
3. Enable Secure Boot in your system configuration by setting `aux.bootloader.secureboot.enable = true;`.
4. Rebuild your system using `nixos-rebuild switch --flake .`.
5. Confirm that Secure Boot has been set up properly by running `sudo sbctl verify`:
```sh
Verifying file database and EFI images in /boot...
✓ /boot/EFI/BOOT/BOOTX64.EFI is signed
✓ /boot/EFI/Linux/nixos-generation-355.efi is signed
✓ /boot/EFI/Linux/nixos-generation-356.efi is signed
✗ /boot/EFI/nixos/0n01vj3mq06pc31i2yhxndvhv4kwl2vp-linux-6.1.3-bzImage.efi is not signed
✓ /boot/EFI/systemd/systemd-bootx64.efi is signed
```
6. Reboot into your system's UEFI firmware. An easy way to do this from a running system is to run `systemctl reboot --firmware-setup`. In UEFI, set Secure Boot to setup mode. This will vary by system and UEFI vendor. On a ThinkPad, you can find these settings by selecting the "Security" tab, then the "Secure Boot" entry. Set "Secure Boot" to enabled, then select "Reset to Setup Mode". Save your changes and exit.
- On systems where there is no setup mode, choose the option to erase the existing Platform key, and/or to allow third-party keys.
7. Once you've rebooted into NixOS, run this command to enroll your keys: `sudo sbctl enroll-keys --microsoft`. You should see the following output:
```sh
Enrolling keys to EFI variables...
With vendor keys from microsoft...✓
Enrolled keys to the EFI variables!
```
8. Reboot your system, then verify your keys were installed correctly using `bootctl status`:
```sh
System:
Firmware: UEFI 2.70 (Lenovo 0.4720)
Firmware Arch: x64
Secure Boot: enabled (user)
TPM2 Support: yes
Boot into FW: supported
```
#### Disabling Secure Boot
To disable Secure Boot, just set `aux.bootloader.secureboot.enable = false;` and rebuild the system.
