I'm definiatelly against turning off this check by default. Especially
now, when HAST will hit the tree in a moment and you can share storage
between machines. It would be too easy to shoot yourself in the foot.
Although it might not be good idea to suggest setting this tunable when
hostid doesn't match with printf on the console.
