OMG. I had no idea. I just googled and... My apologies. Gaming is huge on BSD Unix and Linux derivatives. I guess I should have updated my circa 2000 AD knowledge before posting, but in truth, the analogy was too funny once I thought of it, so I may not have been able to resist even if I'd known.
But thanks for insight.
I've been using ElementaryOS, it's an Ubuntu derivative, It's super clean and minimalist, just the way I like it. I also like Fedora, although don't have much experience. Waiting for Black Friday to build a Ryzen VFIO setup, I've been wanting to do one for a while. Absolutely need to use windoze for something? Just load up the VM, and close it when you're done.
I'm disappointed that AMD backpedaled on their VEGA supporting SR-IOV stance. A consumer card that can be used on a host and guest OS at the same time would really help push VFIO into the mainstream. Linux has pearmented everything except the desktop because it's an objectively better OS for everything except trational PC gaming and photo / video editing, having the best of both worlds... that's the dream.
