A customer wants to make it easier to integrate ThinLinc with configuration management systems such as Ansible, Puppet, Chef, Salt etc. One thing the customer identified was that there is no easy way to determine whether a configuration parameter is set to a value without some kind of custom commands or shell expressions. It would be nicer for the system administrator if we could ask tl-config/hivetool to check this for us and simply set the return code to indicate whether the param is set to the given value.
