Eryu, I think I suggested that Marco could remove the "tmp" definition
because it's not used in the script.  Is there some reason to keep it?
The script did start out with a "./new xfs" generation template.

Oh, I bet some helpers depend on it... sorry, my mistake.  Oops.

(though maybe tmp should just get hoisted to the harness and
not be required in every script, but I digress ...)

Thanks,
