Ian Wienand 349e8db2f7 yum-minimal: pre-install base packages 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 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 <https://wiki.openstack.org/wiki/TripleO>`__
that are responsible for building disk images.  They are also used
extensively to build images for testing OpenStack itself, particularly
with `nodepool
<http://docs.openstack.org/infra/system-config/nodepool.html>`__.
Platforms supported include Ubuntu, CentOS, RHEL and Fedora.

Full documentation, the source of which is in ``doc/source/``, is
