I read it a long time ago. The format is interesting, novel certainly. I suppose it's the selling point, over the prose.
To me it seemed like there were many competing "ways" to read it as well. Like a maze, you can go different paths. Do you read it front to back? Niggle through the citations? Thread back through the holes? It's not often you get a book that has this much re-read value.
Yes, but also I would hope that if you have the autonomy to install linux you also have the autonomy to look up an unknown command before running it with superuser privileges.
