==============
Create a minimal image based on CentOS
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 this builds CentOS 7 images. Set ``DIB_RELEASE`` to ``7``
or ``8`` to explicitly select the release.
For CentOS 7, 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``. For CentOS 8, this is set to ``0`` by default as the
system uses NetworkManager by default.
