Building the custom kernel

On a NIX machine:

nix-build '<nixpkgs/nixos>' -A config.system.build.kernel --arg configuration ./custom-kernel.nix

Uploading the kernel as an artifact to Gitea

1. Create a tarball of the built kernel:

tar -czf custom-kernel.tar.gz -C result .

2. Upload the tarball as an artifact to Gitea:

curl -X POST -H "Content-Type: application/octet-stream" \
     -H "Authorization: token YOUR_GITEA_TOKEN" \
     --data-binary @custom-kernel.tar.gz \
     "https://gitea.example.com/api/v1/repos/your-username/your-repo/releases/YOUR_RELEASE_ID/assets?name=custom-kernel.tar.gz"
