Diving into CentOS 7
-
As I’ve re-edited above, it appears the file system footprint was a result of installing CentOS 7 using the default Partition Scheme LVM and the file system, which happens to be XFS.
Switching the install to use Standard Partitions and the ext4 File system for sda1/2/3 results in a fs footprint on par with Debian at 5.5GB. And by footprint I mean .vhdx file size.

Success on all fronts.
I have successfully created a generalized virtual server running CentOS 7.1 with FOG Build 4820. I can dump an image of it onto any hardware we use, mobile, desktop or virtual and it works exactly as desired.
I like it so much I’m making it my new standard.
There were some new hoops to jump through, but the CentOS community and online documentation provided solutions using native commands and features.
I even succeeded with no issues whatsoever in converting my vm development fog from Debian8.2 to CentOS7.1 in about 15 minutes.
I love slaying dragons.
