yum-minimal
Base element for creating minimal yum-based images.
This element is incomplete by itself, you'll want to use the centos-minimal or fedora-minimal elements to get an actual base image.
Use of this element will require 'yum' and 'yum-utils' to be installed on Ubuntu and Debian. Nothing additional is needed on Fedora or CentOS.
The DIB_OFFLINE or more specific DIB_YUMCHROOT_USE_CACHE variables can be set to prefer the use of a pre-cached root filesystem tarball.
