When building Fedora Server base images (such as when building F27
Modular Server), the --noboot option results in the container image
attempting to mount /boot with XFS like the rest of the system.
This results in the image-creation failing.
Since the partitions don't matter in the end (the files are tarred
up and shipped that way), we'll skip this optimization.
