We were getting some subtle issues in fedora-minimal builds that
turned out to be because /var/run was not a symlink to /run.
Upon further investigation, it turns out that yum is creating a
/var/run directory for it's pid file when it starts working in the
empty chroot (which I verified by stracing it)
---
5905 stat("/home/ubuntu/tmp/dib-tmp/image.Ac4VZZsl/mnt/var/run", 0x7ffddffa0330) = -1 ENOENT (No such file or directory)
5905 mkdir("/home/ubuntu/tmp/dib-tmp/image.Ac4VZZsl/mnt/var/run", 0755) = 0
5905 open("/home/ubuntu/tmp/dib-tmp/image.Ac4VZZsl/mnt/var/run/yum.pid", O_WRONLY|O_CREAT|O_EXCL, 0644) = 6

Because this happens *before* we install "filesystem" (the package),
we mess up it's symlinking.
To work-around this, pre-install the trio of base packages (setup,
basesystem, filesystem) with rpm from outside the chroot.

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.
