# common/manifests/defines/config_file.pp -- create a config file with default permissions
# Copyright (C) 2007 David Schmitt <david@schmitt.edv-bus.at>
# See LICENSE for the full license granted to you.

# A simple wrapper to give all configuration files common defaults.
# 
# Usage:
#  config_file { filename:
#  	content => "....\n",
#  }
#
# Examples: 
#
# To create the file /etc/vservers/${vs_name}/context with specific
# content:
#
#  config_file {
#  	"/etc/vservers/${vs_name}/context":
#  		content => "${context}\n",
#  		notify => Exec["vs_restart_${vs_name}"],
#  		require => Exec["vs_create_${vs_name}"];
# }
#
# To create the file /etc/apache2/sites-available/munin-stats with the
# content pulled from a template:
#
#  config_file {
# 		"/etc/apache2/sites-available/munin-stats":
#  		content => template("apache/munin-stats"),
#  		require => Package["apache2"],
#  		notify => Exec["reload-apache2"];
#  }

	file { $name:
		ensure => $ensure,
		# default permissions for config files
		mode => 0644, owner => root, group => 0,
		# really detect changes to this file
		checksum => md5,
	}

		'': { }
		default: { File[$name] { source => $source } }
