   That *is* the point: full VMs each have their own kernel, containers   
   share a kernel. Apple is making a big deal about some kind of   
   shared-kernel approach. I.e. not full VMs.

   Is Apple using the term “VM” to refer to something that is really a   
   “container”? Are you being taken in by that?

   It’s not “Darwin” any more, it’s “XNU”. Which stands for   
   “XNU’s Not   
   Unix”. Did you know that? That the OS you keep going on about how it’s   
   really and officially “Unix”, is built on a kernel that explicitly   
   claims it isn’t “Unix”?
