Funny, I was just checking the comments to see what is was. I see Fallout brotherhood of steel knight guy in power armor, but idk about the thing on the left

Just out of curiosity, how would one do this (in general terms)?

I hope I never have to because I’m sure I would not figure it out lol

idk if this could be subjective, but what do you mean by upstream here? Does that mean it’s included in most distros?
