Right. But you know how to fetch and inspect (yea?) so, I with you that piping random crap to sh is bad. Maybe these snips encourage that behavior.
Tauri is trustable (for some loose definition) and the pipe to shell is just a well known happy-path.
All that to say it's a low value smell test.
Also, I'm in the camp that would rather git clone and then docker up. My understanding is it gives me a littl more sandbox.
