For anyone interested in unikernels for other languages than Go, there's a list over on Wikipedia: https://en.wikipedia.org/wiki/Unikernel#Examples https://en.w

  Why make bootable images, as opposed to docker images? What sorts of applications do you see using this?

    in one case I boot a blob and it comes up with everything it needs and starts functioning immediately. there is no ambiguity in which code is executing since its exactly those bits that I constructed it with, and no external service dependencies. if you work in a model where you never upgrade servers, just bring up new ones and turn down old ones, doesn't it seem cleaner? obviously they both work.

    Hardware level isolation. Or: if you run your docker container as a vm instance; reduced overhead with only the kernel parts you need. Typical docker is just a glorified chroot under a shared Linux kernel. With namespaces it asymptotically approach a bsd jail. But the "easy" way to get some real isolation, is to use hw support for virtualization - but now you need a kernel (software that enable programs to talk via a fixed abstraction to hardware; drivers for real and emulated hw). And you've reinvented 5% of the magic dust that IBM put into mainframes.
