Demo - Remote Deployment

WIP, use at your own risk.

The sdImage built from this flake lacks configuration & cache for compilation. Consequently, if you intend to execute an application not present within the sdImage, such as nix run nixpkgs#cowsay hello, nix will try to build cowsay and all its dependencies from scratch. This can take a long time!

To avoid this, you can deploy your configuration remotely from a high performance machine, this can be done with colmena.

Deploying remotely with colmena

Modify the nix files in this directory to fit your needs.

Then, run the following command to deploy the configuration to your remote server:

# I have uploaded the build cache to cachix, you can use it to speed up builds.
› nix run nixpkgs#cachix -- use licheepi4a

› nix run nixpkgs#colmena apply

Notes on Network Proxy

If you are in a network environment that requires proxy(such as China), you may need to set up proxies or bypass routes to speed up downloads on both your local host and development board, otherwise your NixOS experience may be quite bad.
