--root-label was added with I596104d1a63b5dc6549e8460a1ae3da00165ef04 This sets the ROOT_LABEL environment variable. Over the years how this deploys has become more complex; now this value gets written into DIB_BLOCK_DEVICE_PARAMS_YAML default values, which is then loaded into DIB_ROOT_LABEL. To override this from the environment you need to specify a full DIB_BLOCK_DEVICE_CONFIG -- we don't have a way to just merge in the root label setting. Using the command-line argument is difficult with tools like nodepool where the command-line is baked into something else. However we already have methods for overriding environment variables on dib calls. Several of the other variables here accept default values from the environment, so this is not an outlier. Making ROOT_LABEL also do this allows us to test with non-default root devices in the gate (see the linked change).

Image building tools for OpenStack
diskimage-builder is a flexible suite of components for
building a wide-range of disk images, filesystem images and ramdisk
images for use with OpenStack.
This repository has the core functionality for building such images, both virtual and bare metal. Images are composed using elements; while fundamental elements are provided here, individual projects have the flexibility to customise the image build with their own elements.
For example:
$ DIB_RELEASE=bionic disk-image-create -o ubuntu-bionic.qcow2 vm ubuntuwill create a bootable Ubuntu Bionic based qcow2
image.
diskimage-builder is useful to anyone looking to produce
customised images for deployment into clouds. These tools are the
components of TripleO that are
responsible for building disk images. They are also used extensively to
build images for testing OpenStack itself, particularly with nodepool.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.
