Environment
A dedicated environment is made available for interacting with the primary GPG key that I utilize across my environments. It consists of an air-gapped Raspberry Pi with the necessary tools made available by NixOS. The image is generateed on my development machine and flashed to an SD card for the RPi to boot with.
Setup
To create the environment, start by cloning the configuration files:
Ensure that multipass is running and then run the following script:
The script will create a new multipass instance and mount the repository
contents to it. Once the instance is running, proceed with the following script:
The script will execute nix build on the instance which will build the raw
NixOS image file. The file will be copied to the local directory when finished.
Extract the compressed image:
Plug the RPi SD card into the local machine and verify it's device name:
Finally, flash the image to the SD card:
Insert the SD card into the RPi and boot.
