dracut has a "hostonly" mode where it builds an initramfs that is suitable for booting the system it is building on. This is on by default, but obviously in our nested multi-platform chroot situation this is fraught with danger. As highlighted by [1] our builds were inadvertently turning off "hostonly" mode when the mountpoints in the chroot were not found. The CentOS 7.3 behaviour change broke this and we ended up with an initramfs with no file-system modules. Iaf2a1e8470f642bfaaaad3f9b7f26cfc8cc445c9 introduced a regeneration of the initramfs, which I think does work as described because it runs in the loopback device. However, dracut includes a package that installs configuration overrides to build a generic initramfs. This is really what we want, and should solve the problem no matter where the initramfs is created. Add this package into yum-minimal and remove the extra re-create call which should not be necessary.

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.
