Funny, I meant “far, far from a Linux expert”!

I should mention that I am trying to setup FOG in a VMware ESXi 5.5 free edition with the VM hard drives (3) setup via iSCSI to a Lenovo NAS. I want the FOG software running on sda, the images of client computers stored on sdb, which I have mounted to /home/images, and the snap-ins stored on sdc, which I have mounted to /home/snapins.

CentOS 8
FOG 1.5.9
New install

Following the installation instructions at https://wiki.fogproject.org/wiki/index.php?title=CentOS_7
When I get to ./installfog.sh it works fine until it gets to “Setting up and starting NFS Server” and that fails with the error messages:

“Unit nfs-kernel-server.service could not be found.”
“Failed to enable unit: Unit file nfs.service does not exist.”
“Failed to stop nfs.service: Unit nfs.service not loaded.”
“Failed to start nfs.service: Unit nfs.service not found.”
“Unit nfs.service could not be found.”

I am far, far from a Linux n00b, even, I literally haven’t touched Linux in at least a decade. I’ve followed the exact installation instructions for FOG. What am I missing?
