When using simple-init, we are making an explicit choice along the lines of "I want the simple tool to do the simple needful" which works well, except when cloud-init tries to run because it is already baked into the source image diskimage-builder started with. So what would happen is Glean would execute from simple-init, and then cloud-init would get launched by default, and cloud-init in some cases everything is DHCP, so suddenly any static configuration, such as what might be in an attached configuration drive, is stomped upon resulting in an unreachable instance if DHCP is just not available. If DHCP is available, generally this is not an issue and goes un-noticed, yet can add a substantial amount of time to the boot sequence "waiting" for meta-data endpoints which may not exist.

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.
