So it's basically like tini (keep a single executable running), but in Rust?

Yep. The less C code in production the better.

		Of note, it also will handle platform specific bring-up system calls, basic filesystem setup, etc, so it is much more suitable for embedded, server, or enclave use cases than tini, imo. It is mostly used for Nitro enclaves today.
