  - The ssh connection plugin will force psuedo-tty allocation via -tt when scripts are executed. psuedo-ttys do not have a stderr channel and all stderr is sent to stdout. If you depend on separated stdout and stderr result keys, please switch to a copy+command set of tasks instead of using script.
