 The tarballs published by Canonical, referenced by `dist-*` tags in https://git.launchpad.net/cloud-images/+oci/ubuntu-base Git repository, are built from scripts that live in [the livecd-rootfs project](https://code.launchpad.net/~ubuntu-core-dev/livecd-rootfs/+git/livecd-rootfs/+ref/ubuntu/master), especially `live-build/auto/build`.
