I am trying to rewrite a file using puppet with the following function.

If the file exists I still want the file to be rewrite from the source. Will this be achieved with the following method?

define setup_sysctl_conf( $dependence=File[$dummy_dependence_file] )
    file { $name:
     path    => '/etc/sysctl.conf',
     ensure  => present,
     mode    => 0777,
     source  => '/vagrant/files/sysctl.conf',
     require => $dependence,

I want to make sure I understand you correctly. If /etc/sysctl.conf does not exist, you want to create it. If /etc/sysctl.conf does exist, you want to rewrite the content to match your source. Is that correct?

If so, then you can re-write your requirements to be, "make /etc/sysctl.conf match my source."

file { '/etc/sysctl.conf':
  ensure  => present,
  owner   => 'root',
  group   => 'root',
  mode    => '0777',
  source  => 'puppet:///vagrant/files/sysctl.conf',

You need to make sure your file source is configured in fileserver.conf as a mount point, or located in a module.

what is the difference apart from the source 'puppet//'. Does the 'puppet//' not mean the file has to be on a puppet node?

The puppet master can only source files that exist on the puppet master itself. Further, the files that are being sources either have to be in a module, or in ...(more)
