RPM Specs and scripts to manage the PEP as a service.
No, it's simply wrong :) That if is supposed to check whether the Context Broker is installed or not, to restore it to its original port. It happens to work because the config file will not be present if the package is not present, but there may be cases where that's not true (if the package was uninstalled but the config file remained here for whatever reason). I'll add a proper package existace check.
