The old FreeBSD master Vi was praised by many sysadmins for his perfect understanding of FreeBSD and pure life.
Once some youngster decided to test master Vi's knowledge and asked him: "Tell me, oh Master, how did you configure your servers?"
Master Vi answered: "I don't really know".
Disappointed youngster returned to his own master and told him: "Master Vi is just a pretentious old man, he doesn't know anything. I know every configuration file in all of my Linux installations".
His Master gave him a slap upside the head and said: "Master Vi configured his servers when these mountains were still young and this river was but a small spring. He never needed this knowledge again, because his servers have worked flawlessly ever since. This is why his understanding is perfect".
