[puppet]puppet plusignment "+>"

There are other ways to use inheritance. In Puppet 0.23.1 and higher, it’s possible to add values to resource parameters using the ‘+>’ (‘plusignment’) operator:


class apache {
service { 'apache': require => Package['httpd'] }
}

class apache-ssl inherits apache {
# host certificate is required for SSL to function
Service['apache'] { require +> File['apache.pem'] }
}
