It looks like the correct code would be to change the kickstart_kernel_options
from:

  # bond
  if iface.bond? && rhel_compatible && os_major >= 6
    bond_slaves = iface.attached_devices_identifiers.join(',')
    options.push("bond=#{iface.identifier}:#{bond_slaves}:mode=#{iface.mode},#{iface.bond_options.tr(' ', ',')}")
  end

to

  if iface.bond? && rhel_compatible && os_major >= 6
    iface.attached_devices_identifiers.each do |ident|
        @host.interfaces.map do |nic|
            if ident == nic.identifier
                options.push("ifname=#{nic.identifier}:#{nic.mac}")
            end
        end
    end
    bond_slaves = iface.attached_devices_identifiers.join(',')
    options.push("bond=#{iface.identifier}:#{bond_slaves}:mode=#{iface.mode},#{iface.bond_options.tr(' ', ',')}")
  end
