Do you think that once GCC gets a working Wasm backend[1], that it might be possible to build Linux for Wasm directly and skip the RISC-V VM?

With RISC‑V emulation we get the virtual hardware components we need to boot Linux like MMU, registers etc. So a GCC WASM backend could definitely help, but I'm not sure it could replace the whole emulation layer.

So we can run this on a browser? a demo on the github page would be great. combine it with an extension to support networking, and you have a winner.

It doesn't have browser support yet because it's WASI-based, so there are a few more steps compared to Emscripten (two different ways to build for WebAssembly). But networking is supposed to work, did you have trouble with it?

I didn't try it. Given jslinux exists, and works, i suspect WASM based linux will be faster and more streamlined.
