A real solnix riscv64 kernel (OpenSBI → kernel → init → shell)
running in a WebAssembly RISC-V emulator. Try ls,
cat /etc/release, echo hi.
Heads up: this is a demonstration image — its runtime linker prints a few [ld.so.1] proof lines before every command (that is the kernel showing its work, not an error), and the minimal /bin/sh has no pipes or > redirection. Yes, there is an /etc (try ls /etc).
