As an admin, I need the EXIF tool supported as a command line resource

Modified both the UCT route and the Derivatives route. There turned out to be four calls direct to the exif tool of which I was unaware. In three exif is being used as a conversion tool like ImageMagick. The last is to duplicate metadata to a blurred image. The exif tool can be called from within the FITS Docker container but at this writing we don't know the speed of such calls. However, it is practical to install it as a standalone O/S service too. I need to know if the metadata being duplicated in for blurring is in the FITS report or really needs the exif tool.

On completion of this work the derivatives route will not need FITS installed locally on the SMX host.
