So, this weekend I'm playing with Fiwix. Fiwix (https://fiwix.org/) is a small hobbyist operating system for i386 that aims to be Linux 2.0 compatible while being small enough that a single human could understand it as a whole (it's ~30k SLOC, self-hosted, and can be built with tcc).

A couple of years ago Fiwix was used in a fun project of "let's bootstrap a Linux system with only tiny tools that can be understood by a single person": https://github.com/fosslinux/live-bootstrap/blob/master/parts.rst

My refreshed interest in it comes from multiple sources: first, there is now a TCP/IP stack (still WIP). Second, GNU/Linux is *gestures ambiguously* in a strange state, so it is interesting to see how far one could get with a completely non-BSD non-standard tiny, toy-like operating system.

The installation is quite straightforward. "Please keep in mind this kernel is not yet suited for production. Use at your own risk!" is, in itself, a proof of reliability.

This is a beginning of a slow-going🧵
