Monty Taylor af2862a2be Add minimal ubuntu and centos base elements
There are times when a much more stripped down base image is desired
over the distro cloud images. For instance, Infra would like some base
images that do not have cloud-init or really much of anything else. This
is easy to accomplish with debootstrap and rinse.

Create a minimal image based on Ubuntu. We default to trusty but DIB_RELEASE is mapped to any series of Ubuntu.

If necessary, a custom apt keyring and debootstrap script can be supplied to the debootstrap command via DIB_DEBIAN_KEYRING and DIB_DEBIAN_DEBOOTSTRAP_SCRIPT respectively. Both options require the use of absolute rather than relative paths.

Use of this element will also require the tool 'debootstrap' to be available on your system. It should be available on Ubuntu, Debian, and Fedora.

The DIB_OFFLINE or more specific DIB_DEBIAN_USE_DEBOOTSTRAP_CACHE variables can be set to prefer the use of a pre-cached root filesystem tarball.

The DIB_DEBOOTSTRAP_EXTRA_ARGS environment variable may be used to pass extra arguments to the debootstrap command used to create the base filesystem image. If --keyring is is used in DIB_DEBOOTSTRAP_EXTRA_ARGS, it will override DIB_DEBIAN_KEYRING if that is used as well.
