When extracting the base image without --numeric-owner, user and group
names in the tarball are mapped to uid/gid by the host. This can cause
problems when building an image for some other distro than you're
running yourself. For example, building an Ubuntu image on openSUSE
ends up with /var/cache/man in the image owned by 'proxy' (uid 13)
instead of 'man' (uid 6), because the host (openSUSE) uses uid 13 for
the 'man' user. This particular man/proxy discrepancy results in
"fopen: Permission denied" errors when apt-get does its "Processing
triggers for man-db" thing in the Ubuntu system. I wouldn't be
surprised if there were other kinks caused by this uid/gid mapping
discrepancy too, but that's the one I found so far.
The same thing can also happen with Fedora, but seems to be less likely,
or at least less obvious to me when building Fedora images on openSUSE.
But, IMO, it's better to be safe and just use --numeric-owner on all
base image untarring outside the chroot.

The code to handle unregister of RHEL subscriptions was buggy and
broke if no subscription credentials were supplied.

If you want to have the installation update packages, you'll
need to register the system log in to rhn and subscribe to an
available subscription.
export DIB_RHSM_USER to your rhn username
export DIB_RHSM_PASSWORD to your rhn password
To get the qcow2 image, log into rhn.redhat.com and download the
image from
https://rhn.redhat.com/rhn/software/channel/downloads/Download.do?cid=16952
Then export DIB_CLOUD_IMAGES to whereever you're hosting the qcow2.
