Without this change, puppetting an infracloud machine from scratch results in an error[1]. The order of events that causes this issue is: 1) Puppet purges /etc/apt/sources.list, removing all of apt's knowledge of other sources 2) Puppet creates /etc/apt/sources.list.d/openstack-infra.list, but this will have no effect on apt's knowledge of other sources until an apt-get update is run 3) The puppet-openstack_extras module runs an exec to install the ubuntu-cloud-keyring package. (This is done with an exec type rather than a package type because it needs to be run before Exec['apt_update'] which is defined in the puppetlabs-apt module.) Since apt at this point knows of no apt sources in the world, it fails to find the package. 4) Apt-get update is run and the world is right again, so subsequent puppet runs or manual installs of ubuntu-cloud-keyring are confusingly successful. A potential fix for this is to create another exec resource that runs apt-get update after adding openstack-infra.list but before installing ubuntu-cloud-keyring, after which apt-get update will run once again. This is inefficient and ugly. Since on these particular nodes we control the base images, and the default apt sources list is sane and matches what we have set in openstack-infra.list anyway, we can just disable the purging of the original sources.list and there will no longer be any point during which apt has no sources.

Puppet Modules
These are a set of puppet manifests and modules that are currently being used to manage the OpenStack Project infrastructure.
The main entry point is in manifests/site.pp.
In general, most of the modules here are designed to be able to be run either in agent or apply mode.
These puppet modules require puppet 2.7 or greater. Additionally, the site.pp manifest assumes the existence of hiera.
