> Why not? Most people won't spend the time to learn OS/distro building. I don’t know how good they are and have never used any, but there’s tooling for building the ultimate stripped down kernel, unikernels (https://en.wikipedia.org/wiki/Unikernel) A quick Google gives me https://nanovms.com/, https://github.com/solo-io/unik and https://github.com/rumpkernel/rumprun. A disadvantage of such a stripped down system is that debugging such a system can be difficult. For example, if there’s only one process, you can’t open a shell to look around on a misbehaving system.

Great entrant in the space that is actually usable with ergonomic tooling and good docs: https://www.unikraft.org Promising project that's inactive but was one of the first ones I found with reasonable ergonomics and no lock-in to a specific language that I didn't use: https://github.com/rumpkernel/rumprun Unfortunately it looks to be unmaintained as of now, but I expect the examples still work etc (https://github.com/rumpkernel/rumprun/issues/135)

While that's true, the flip side is that "traditional" kernels have much better hardware (and general) support because they benefit from the long history of the "main project". Stripping down traditional kernels to work as unikernels is not a new thing: https://github.com/rumpkernel/rumprun

Rumprun[0] is another big one in the C camp. Though I think you can use basically any software that conforms to posix. [0] https://github.com/rumpkernel/rumprun/

Forget Docker, the future is unikernels! [0] I haven't gotten to play with them much, and the ecosystem is very, very young, but the idea of it all is very intriguing to me. [0] https://github.com/rumpkernel/rumprun

Not a whole lot, tbh, The idea is to run directly on the hypervisor/hardware, and they both do that. In actuality they're pretty far from each-other but conceptually they are the same. Here is the rumprun unikernel: https://github.com/rumpkernel/rumprun

I didn't quite get what a unikernel was. Reading up on approaches that were a bit different than MirageOS was helpful: http://osv.io/ https://github.com/rumpkernel/rumprun

This is the only unikernel I know of that supports "raw" applications - OSv applications run in a JVM and MirageOS applications are in OCaml. Edit: looks like there's a direct alternative called Rumprun: https://github.com/rumpkernel/rumprun. I hadn't heard of it. Anyway, right now this whole unikernel thing is still pretty new so it's good to have multiple projects.

What I want to know is how this is better/different compared to Rumprun or OSv. They appear to be its closest competitors. https://github.com/rumpkernel/rumprun/ http://osv.io/
