While extending a puppet module which should manage /etc/network/interfaces I am facing the following problem:

The old module just reads some vars from hiera and creates the file with one interface through a template. To remove this limitation I added a hash to hiera containing other interfaces and their params. Through the puppet-concat module I want to add them to the interfaces file.

But if first the file for the template and later the file for the concat gets declared a Duplicate declaration error is thrown.

How can I first use the template and later concat to the file? Or is this not possible?

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Resource Statement, Duplicate declaration: ..../modules/lip_network/manifests/debian.pp:16 cannot redeclare at /etc/puppetlabs/code/modules/concat/manifests/init.pp:179 at .../init.pp:179:5 at .../modules/lip_network/manifests/debian.pp:21

Class Code:

class lip_network::debian
  $ipaddress  = $::lip_network::ipaddress
  $netmask    = $::lip_network::netmask
  $gateway    = $::lip_network::gateway
  $dns1       = $::lip_network::dns1
  $domain     = $::lip_network::domain
  $iface      = $::lip_network::iface

  package { 'resolvconf':
    ensure  => latest,

  file { '/etc/network/interfaces':
    mode    => '0644',
    owner   => 'root',
    content =>  template("${module_name}/interfaces.erb"),
  concat { '/etc/network/interfaces':
    ensure => present,
  $interface_configs = hiera_hash(lip_network_multi_interfaces::interfaces)
  $interface_list = keys($interface_configs)

  concat::fragment { "test_interfaces":
      target  => '/etc/network/interfaces',
      content => 'auto em0\niface em0 inet static',
      order   => "10"

  # apparently /etc/init.d/networking does not regenerate
  exec { 'iface restart':
    command     => "ifdown ${iface} ; ifup ${iface}",
    refreshonly => true,
    subscribe   => File['/etc/network/interfaces'],

I don't think you can do that, and again, it's much better to have all of this stuff inside the template. There's still no need to be using concat fragments here.
