Recently on HN (I think) and related: - https://micromind.me/en/posts/from-docker-container-to-boota... - https://godarch.com/ Really like seeing these new usecases for containers -- would have never thought to mix the two technologies in this way.

Darch reminds me a bit of Tiny Core Linux. That uses loopback images for packages, and puts them together with UnionFS, IIRC.

Well, containers and VMs are two different things (are they not?).

They are different, yes.

They seem to do very little that SystemD cannot already do with services and overlayFS, with the added benefit of being already available on most systems.

Why JavaScript instead of something more performant?

What for? It's just glue code, it doesn't actually run the micro-VMs.

Would be really cool to use this to predictably build images for booting from PXE.

Normally the language for doing this kind of system building would be .. Bourne shell. Or Perl/Python.

On the same vain, there is: https://github.com/vmware/vic a docker engine for esx/vsphere.

Note work at VMware but not on this project.

This is great! I really wish we'd always create a single system image for both Docker and Physical/VM, preferably with minimal/no-init.

This is very useful when trying to create a basic datacenter specific distro/deployment, preferably Pixie bootable as well.

Yes, but the cool thing is definitely the single system image
