This means ./guix-install.sh doesn't work on e.g. NixOS. :-)
Please use /usr/bin/env bash.
The manual workaround is obvious, but this is a thousand-papercuts bug.

/usr/bin/env wouldn’t work on Guix System by default. :-)
What about something like this:

“guix-install.sh” arguably would not primarily be executed on a Guix
