Right, on both Fedora and RHEL nfs-blkmap.service is disabled by default
(via /usr/lib/systemd/system-preset/99-default-disable.preset) because
we support SCSI layout but not block layout.  I could have sworn I've
floated the idea of dropping blkmapd from the Red Hat packages
altogether, but I can't find anything in Bugzilla or Jira.
