Ian Wienand 4585955a8b Remove yum chroot caching
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 ubuntu

will 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.
