> But what jimktrains2 suggesting is complete opposite of that, it reduces options.
Personally I'd consider having familiarity with more than one platform would increase one's options.
But ultimately having other solutions on the market is a good thing. Not only because no one solution is the best at every metric (be it stability, security, speed, memory usage, nor any specific requirements), nor because different solutions can appeal to different personalities. But mostly because different solutions might solve a problem in a unique way that the competing solutions may not have considered - often in ways that can ported and thus benefit the competitors and wider community.
So I wouldn't be so quick to dismiss anything that's outside your field of expertise.
What you're talking about is a luxury I can't afford. That's what I mean when I talk about the price. There are plenty of far more important technologies that I would rather learn.
I can't afford to learn two technologies that do about the same thing, of which one is significantly less popular, might now have tools that other has and runs on a significantly less popular OS.
That's actually a fair point and one I completely sympathise with. But your original argument very much sounded like you were suggesting that people in general shouldn't bother with FreeBSD, jails, nor any other technologies which weren't dominant in their respective field. Which is why we disagreed.
