Build WireGuard tools and kernel modules for CoreOS using Vagrant, following coreos/bugs#2225 (comment)

Setup

Vagrant plugins

vagrant install vagrant-sshfs

Install sshfs on your host system too.

Downloading an appropriate developer image

You need a developer image that matches the Vagrant box you're going to run. ./fetch-dev-container will download the latest stable dev container.

If you're really bored, feel free to bunzip2 it and lz4 the image.

For each run

rm -rf output
mkdir output

(This is necessary as some sshfs implementations will whine about non-empty directories.)

vagrant up

Be patient

The line that starts systemd-nspawn --bind="$PWD:/host" hangs for approximately three minutes for some reason.

Output

In the output directory is a torcx package. Info on using it can be found at the GitHub thread.
