Puppet::Type.newtype(:file_line) do
desc <<-EOT
Ensures that a given line is contained within a file. The implementation
matches the full line, including whitespace at the beginning and end. If
the line is not contained in the given file, Puppet will add the line to
ensure the desired state. Multiple resources may be declared to manage
multiple lines in the same file.
Example:
file_line { 'sudo_rule':
path => '/etc/sudoers',
line => '%sudo ALL=(ALL) ALL',
}
file_line { 'sudo_rule_nopw':
path => '/etc/sudoers',
line => '%sudonopw ALL=(ALL) NOPASSWD: ALL',
}
In this example, Puppet will ensure both of the specified lines are
contained in the file /etc/sudoers.
