This makes sense. Linux should be forward thinking but can't break
compatibilty with other operating systems (several of my user

If Microsoft Built Cars: Every time they repainted the
lines on the road, you'd have to buy a new car.
Occasionally your car would just die for no reason, and
you'd have to restart it, but you'd just accept this.
