Title:
  nfsd won't start unless exports has content

Status in nfs-utils package in Ubuntu:
  Confirmed

  +       export_files="/etc/exports"
  +       for file in /etc/exports.d/*.exports ; do
  +               if [ -f "$file" ]; then
  +                       export_files="$export_files $file"
  +               fi
  +       done
  +       if [ -f /etc/exports ] && grep -q '^[[:space:]]*[^#]*/' $export_files
          then
                  do_modprobe nfsd

  It is no longer possible to start nfsd without content in /etc/exports
  (or /etc/exports.d/*), making it impossible to create temporary
  exports (ie - using exportfs) if the host does not have permanent
  exports.  This also breaks other alternative management tools that
  eschew /etc/exports, like ZFS.
