The output of the command in testing._execute()

    # Execute command and catch any exception
    def _execute(self, cmd):
        """ 
        Execute command
        """ 
        # Execute command, make sure we catch any exception
        try:
            rc = os.system(cmd+' >/dev/null 2>&1')
        except:
            rc = -1

        # Return return code
        return rc

should not go into /dev/null but should be recovered so that in case of an error the result can be traced down somewhere. For the moment it’s very difficult to understand what went wrong.
