What is a “medical injury”? When the surgeon slips?

I’m fairly certain you could still run that shell script on steamOS? I don’t understand why an immutable distro would keep you from doing that. It’s essentially what Lutris and Heroic Games launcher do.

It’s also possible the entire white part just ripped off my board somehow and stuck to the wire.

That’s exactly what I think I’m seeing here.

Maybe Publii?

Are you talking about an ultrasonic humidifier? AFAIK, those shoot out tiny water particles along with any bacteria that might be present, creating a health risk. You’re meant to only use distilled water with those.
