> wondering if at this point we need an OS at all People have written unikernels, but they're not that interesting anymore when you can trivially constrain Linux to a single core, keep the remaining cores for you app (no context switching), and keep all of the Linux-y goodness for admin and debugging (SSH, gdb, etc.). All of the performance, none of the admin and deployment headaches. Basically, unless you truly can't afford that extra core, unikernels are all downside at this point.
