If that was true then no six year old boy, let alone, his five year old sister, could possibly install a Linux distribution!
Here is an article from a 'mere' woman (who just happens to head up a very successful company selling Linux boxen), about her 5 and 6 year old children installing Linux, and getting stuck in to assembling computers:
One early spring day as we were walking home from the bakery on the corner, we passed by a neighbor and struck up a conversation. He complained about his desktop being constantly attacked by viruses. We suggested Ubuntu. A professional man in his 50s, he said he wanted to try installing a Linux distribution on his desktop but that, “it looks too complicated. I probably couldn’t install Ubuntu. I don’t want the hassle.”
My little five year old daughter had been snuggled in my arms while I was talking to this neighbor. She had been listening closely. When we got home, she said, “Mom, I can install Ubuntu. I bet I can. Can I try? Can I try?”
