Cloning the kernel repository

This repository clocks in at over 3 GB of disk usage, so you might want to clone it as a shallow clone:

git clone --depth=1 https://github.com/rtr7/kernel

Updating the kernel

First, follow the gokrazy installation instructions.

We’re using docker to get a reproducible build environment for our kernel images, so install docker if you haven’t already:

sudo apt install docker.io
sudo addgroup $USER docker
newgrp docker

Clone the kernel git repository:

git clone --depth=1 https://github.com/rtr7/kernel
cd kernel

Install the kernel-related gokrazy tools:

GOBIN=$PWD/_build go install github.com/gokrazy/autoupdate/cmd/gokr-rebuild-kernel@latest

And build a new kernel (takes about 5 minutes):

(cd _build && ./gokr-rebuild-kernel)

The new kernel is stored in the working directory. Use gok add . to ensure the next gok build will pick up your changed files.
