  current = [] if current == :absent

  message = ''
  message += "removing #{(current - should).join(', ')} " unless (current - should).inspect == '[]'
  message += "adding #{(should - current).join(', ')} " unless (should - current).inspect == '[]'
  #
  # If the array contains the same value twice e.g.  compare ['Server','Server'],
  # the current algorithm returns an empty string. In that case we use the full value.
