Yeah looks like it's installed by default. Can't find an official announcement/changelog but according to an unsourced reddit thread it's been there since steamos 3.5.
It is not. From a quick poke around and watching the video, it looks like it's a bit of a joke and just includes existing games such as Crossy Road.
More like a rail-replacement bus. Your child can't make it to school today so we sent the dog.
Can't you just use distrobox directly on steamos to save changing os?
The state police and the cyber police, I reckon
Also the episode was removed from streaming before Disney bought Fox
They're just asking questions, no need to get sexual about it
Yeah I don't like it when they remove what are essentially accessibility features in the name of their artistic vision. A classic is something like limiting when you can pause the game.
I guess it's a design decision so people don't save-scum, but losing your whole game highlights a pretty massive issue with that design

Apparently distrobox come pre-installed. Also I don't think there's any rpm-ostree on steamos, that's a Fedora Atomic thing.
