IDK, probably a lot.

I like a lot of Ubuntu-based distros, and Ubuntu server, but Ubuntu desktop just wasn't for me!

Those mushrooms are not deadly, they are hallucinogenic. People do in fact eat them for recreation, and berserkers used to take them in battle. Fly agaric is only deadly when its mycelium has been crossed with its sibling, the death cap, this creating a deadly hybrid. The psychedelic properties of fly agaric can be neutralized by boiling the mushrooms in salt water, do not try at home.
