LVM

I have two machines which are my original two CentOS 7 installs, which date back several years. At that time, I was running an old (now ancient) version of cobbler which had a history of blowing up when I tried updating to newer versions (more on that in a different, future post), and there was no support for RHEL/CentOS 7 installs using it. And I don't mean that it was just missing the "signatures" and what defines an OS version to cobbler... the network boot just went ***BOOM*** as it was bringing up the installer.
