# Usage:
|
|
# line { description:
|
|
# file => "filename",
|
|
# line => "content",
|
|
# ensure => {absent,*present*}
|
|
# }
|
|
#
|
|
# Example:
|
|
# The following ensures that the line "allow ^$munin_host$" exists
|
|
# in /etc/munin/munin-node.conf, and if there are any changes notify the service for
|
|
# a restart
|
|
#
|
|
# line { allow_munin_host:
|
|
# file => "/etc/munin/munin-node.conf",
|
|
# line => "allow ^$munin_host$",
|
|
# ensure => present,
|
|
# notify => Service[munin-node],
|
|
# require => Package[munin-node],
