dracut has a loop [1] where it probes top-level directories, tries to find what block device they are on, then determines the file-system of that block device. It then puts those file-system modules into the initramfs for boot. Since we install the kernel package during the chroot phase, / there is not a block device and thus this loop matches nothing and we end up with no file-system modules in the initramfs. This results in a very annoying silent boot hang. By moving re-generation of dracut into finalise.d phase, we run inside the final image where / is the loop-device; the root file-system gets detected correctly and the ext4 module is included correctly.

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=trusty disk-image-create -o ubuntu-trusty.qcow2 vm ubuntuwill create a bootable Ubuntu Trusty 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.
