Add an environment variable to control the creation of eth0/1 interface enablement scripts. With a tool such as glean, the presence of these scripts will indicate the interface is configured and configuration-drive settings will not be applied. This means in a non-dhcp situation like on Rackspace, network is broken. On Fedora, where later systemd provides "predictable network interface names" [1] eth0 & eth1 ironically aren't predictable so this just confuses things. You really need cloud-init or glean or something to bring up your interfaces in a sane fashion. This maintains the status-quo on centos-minimal, but disables creation for fedora-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.
|
|
|
|
This element cannot be used with the base element, therefore must pass the -n
|
|
flag to disk-image-create when using this element.

|
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.
|
|
|
|
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`.
