Yeah we only recently broke it out as a standalone repo/binary, as everyone historically vendored it, so docs will get love soon, but it will be part of the next stagex release built and signed by multiple parties deterministically as stagex/user-nit.

To run it all your need to know is put it in your filesystem as "/init" and then add this to your kernel command line for the binary you want nit to pivot to after bringing the system up:

nit.target=/path/to/binary

That's it. Minimum viable init for single application appliance/embedded linux use cases.

nit and your target binary are the only things you actually need to have in your CPIO root filesystem. Can be empty otherwise.

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

>>nine_k+d1
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.
