Using raw in the middle of a partition squashes chain name on generated rules

[gergnz]

partition 'x' do
  label 'a', :address => '10.243.4.97'
  label 'b', :address => '10.243.4.3'
  rewrite 'do a dnat' do
    protocols 'tcp', 'udp'
    ports 6050, 6051, 41524
    dnat  'a' => 'b'
  end
  raw <<-RAW
iptables -t nat -I INPUT -j ACCEPT
  RAW
end
