Puppet notes

Built-in puppet variables in templates:

# This file is controlled by Puppet
# /etc/puppet/puppet.conf
# <%= scope.lookupvar('::osfamily') %> <%= scope.lookupvar('::operatingsystemmajrelease') %>

Example of template and file:

    file { "/etc/puppet/puppet.conf":
           owner => "root",
           group => "root",
           mode  => 644,
           content => template("puppet/puppet.conf.erb"),
           notify  => Service["puppet"],
    }

    file { "/etc/sysconfig/puppet":
           owner => "root",
           group => "root",
           mode  => 644,
           source => "puppet:///modules/puppet/puppet",
           notify  => Service["puppet"],
    }
