# common/manifests/defines/line.pp -- a trivial mechanism to ensure a line exists in a file

|
# Ensures that a specific line is present or absent in a file. This can
|
|
# be very brittle, since even small changes can throw this off.
|
|
#
|
|
# If the line is not present yet, it will be appended to the file.
|
|
#
|
|
# The name of the define is not used. Just keep it (globally) unique and
|
|
# descriptive.
|
|
#
|
|
# Use this only for very trivial stuff. Usually replacing the whole file
|
|
# is a more stable solution with less maintenance headaches afterwards.
|
|
#
|
|
# 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];
|
|
# }
