Every run we are doing a full tar.gz of the chroot environment that never gets used. It's not suitable for CI since we use fresh images each time there. The cache in general isn't really isn't a very safe thing to have around, because there's no invalidation procedure and no real way to make one -- we've no guarantee that a new chroot build even moments after a previous one wouldn't bring in or different packages, etc (of course this is *unlikely*, but the longer you go between builds the worse the problem becomes. Also, tons of packages get installed after this not from any cache, so potential speed-up is rather marginal. Debian turned this off with I58fc485aacacaa17243bf9ce760ed91256d1f182. However, given the reasons above and it's complete lack of testing, I don't see this as useful. If we really want this type of thing, I think we should come up with a way to use a persistent external yum/dnf cache that yum/dnf keeps in sync with it's usual invalidation rules.

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.
