Ubuntu Release
This repo hosts the tooling used to generate Ubuntu images hosted on the not yet existing https://images.ubuntu.com.
DISCLAIMER: this is very early work, as we're trying to move away from a very manual process and setup on https://cdimage.ubuntu.com. This repo is still very much the future, and not everything is clearly defined yet. If you want to submit feature requests, please make sure you already understand Ubuntu's release mechanisms, and have a strong use-case in mind to show that it needs to be taken into account early.
