Although an option, the main motivation here to remain consistent with how it works in GitLab. Since we define SCRATCH_DIR under the 'vars' section, IIRC you can only use a scalar value, not a command (if we can, I retract my argument) and hence we'd have to export and define the variable under each script, before_script, after_script sections.

So, I preferred consistency here, since I wouldn't realistically expect an engineer to have /tmp/scratch prior to executing script given the main motivation here is to quickly get a throwaway test machine to run the script and THEN debug if the tests fail. So, while I agree you're right here, I don't think it's a likely scenario. Erik
