I do a daily update of the context distribution using the command
sh ./first-setup.sh --modules=all --engine=luatex

This works well, but is rather verbose on the screen.
Would it be possible to have a less verbose version?
Or that the script could check some kind of a checksum before deciding
to download all data? Or download only part of the data (saving on some
carbon footprint ;-)

Thanks.
