Not quite, but

  $ echo -e "y\ny" | guix-install.sh

will. Or the more conventional

  $ yes | guix-install.sh # untested

providing guix-install.sh doesn't choke on that infinite stream of 
"y"s. Which it might, and even if it doesn't now, there's no 
guarantee that this dirty hack won't break the future.

If this is something we want to support, it could be done more 
better through a '--non-interactive' or '--force' flag that skips 
these and any future prompts at the source.

Non?
