2 years ago hi @frank-dspeed. this will be a completely different project then with completely different goals and layer upon layer of added complexity, which is exactly what i want to avoid. i'm all for someone like yourself having a look at doing this as a separate project that builds on top of just-js and happy to help/advise with the effort but i don't ever see it becoming part of the core.
i have done some experiments with building a full "unikernel" VM in javascript with just-js - using firecracker or lkvm. this is possible with just-js out of the box as a separate project and i think would be a better direction to go in. i'll see if i can clean up these experiments and write them up on the blog in coming weeks. if what you want is a bundled OS/runtime/application in a single binary that launches a linux kernel on kvm then take a look at these.

there is also an lkvm module here that works but i need to write up some examples/docs for it and tbh lkvm is not maintained anymore afaik so it's more of a proof of concept than anything.
At Present this projects offers single binary builds to executeable
how ever we could merge the abondoned runtime-js project which is a minimal c++ kernel to boot v8 this gives us just-js as unikernel
so we can directly deploy it without needing a additional OS
it is not much code and it is inside the philosophie of this project to be educational
