============== centos-minimal ============== Create a minimal image based on CentOS 7. 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. By default, ``DIB_YUM_MINIMAL_CREATE_INTERFACES`` is set to enable the creation of ``/etc/sysconfig/network-scripts/ifcfg-eth[0|1]`` scripts to enable DHCP on the ``eth0`` & ``eth1`` interfaces. If you do not have these interfaces, or if you are using something else to setup the network such as cloud-init, glean or network-manager, you would want to set this to ``0``.
