1. I have a class: class templates-services-lamp-class { ... # set a default password for all MySQL installations, can be overriden per server $root_mysql_password = "password" # if the password is not set (= blanco), set it to $root_mysql_password, otherwise do nothing exec {"Set MySQL server root password": require => Service ["mysql"], onlyif => "mysqladmin -uroot status", command => "mysqladmin -uroot password $root_mysql_password", } file {"/tmp/testfile": ensure => present, owner => root, } ... } 2. On another place in my file structure I have: class classic-shared-database-mysql-class { # base include templates-base-crontab-class # include templates-base-disactivate-services-class include templates-base-network-class include templates-base-scripts-class # include templates-base-tools-class # service # include templates-services-bind-class # include templates-services-courier-pop3-class # include templates-services-dovecot-pop3-class include templates-services-lamp-class <---------------- # include templates-services-lighttpd-class # include templates-services-ntpd-class # include templates-services-postfix-class # include templates-services-pptp-class # include templates-services-proftpd-class # include templates-services-syslog-ng-class } 3. Then I define my node like this: node testpuppetclient { include classic-shared-database-mysql-class } Now my node has all the classes to be a 'generic sql server' Now for my question: I want to override the mysql password on server level. I know a subclass can only override resources defined in a parent class, so this should work: node testpuppetclient inherits templates-services-lamp-class { $root_mysql_password = "other_password" } but it DOES NOT. Can you not override a variable then ? 4. Wat *does* work, is something like: node testpuppetclient inherits templates-services-lamp-class { File["/tmp/testfile"] { owner => someone_else } }
