I built an image with stack image container in a subdir and I see a left-over cruft directory left behind in the sub-directory. ``` % find .stack-work .stack-work .stack-work/image .stack-work/image/0 .stack-work/image/0/usr .stack-work/image/0/usr/local .stack-work/image/0/usr/local/bin .stack-work/image/0/usr/local/bin/xyz .stack-work/image/0/Dockerfile ```
