Gokrazy doesn't expect you do to anything through FFI or shell commands, though. The whole idea is you write your entire app in Go. The kernel, the Go runtime, and a little bit of gokrazy utility/glue code (e.g. bringing up the network and doing DHCP) are the entire platform.

Edit to add: it would actually be difficult to do FFI or shell commands within gokrazy since there's no dynamic loader to resolve external symbols when you try to execute a dynamically linked library or program. You'd have to add this feature if you wanted to call out to anything built with a dynamically loaded C runtime (which is damn near everything these days, with one notable exception being Go executables built without CGO).
