It would be ideal if the directories you want to manage this way were located in a parent directory that you could be sure would hold only files for this general purpose. I would not feel comfortable assuming that /opt satisfies that criterion, but you could set up a subdirectory such as /opt/java_version for the purpose.
Next you should consider whether you need the test for which directory is currently symlinked. You're managing the deployment of those directories and (I hope) the symlink itself via Puppet, so you don't really need to test. Instead, you can just rely on Puppet to get it done, or else to fail before any damage is done. For example, you can do something like this: $java_base_directory = '/opt/java_version' $current_java_version = '123456' # Put the current version in place, update the # symlink, etc.; perhaps you have a defined # type that handles it? deploy_java_version { "${current_java_version}": base_directory => "${java_base_directory}" } # Clean up other versions file { "${java_base_directory}": ensure => directory, recurse => remote, purge => true, ignore => "${java_base_directory}/${current_java_version}", require => Deploy_java_version["${current_java_version}"] } You may need also a "source" parameter, but it can (and should) point to an empty directory on the master's file server. There are other approaches you could consider, but other than an Exec, all of them either require you to maintain a list of the directories you want to ensure have been removed, or else to create and deploy a custom fact. Neither of those is hard, but they would be bigger and a bit messier than the above approach. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
