Is anyone playing with this? I read whenever people post this stuff here, and this book is very interesting and I will peruse despite being way above my understanding and I am curious who is doing something crazy with NetBSD which I find fascinating as well since the first toaster jokes I heard.
I think that everyone, thanks to container and general virtualization acceptance are moving in a slightly different direction, but I thought rump kernels and Metasepi (also posted here a few times) blew my mind and thought we can start bootstrapping more secure foundational OS layers below legacy applications Unix has bequeathed us forever.
