What languages do you support for unikernel?
Is it just Go, or do you plan to support others in the future (e.g. OCaml for MirageOS)
1) What languages right now - Go, php, javascript, ruby through the rumpkernel project - rumpkernel.org.
2) We are implementing support to support user supplied images which will let you run mostly anything in the very near future. We plan to be completely agnostic.
