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🧵

FiwixOS comes with quite a few ports, and will require close to 1GB on a disk. I suppose this is because the packages are not particularly optimised in size. The biggest packages beyond the base and GCC are Python3, Perl, ZX Spectrum emulator and Doom/Heretic.

Also, look at this Halt message, so cute!

The system is small, but functional. At the same time, there are quite a few sharp corners, unfinished and untested things.

The list of packages/ports is small, so I want to bring a few things in. Is it going to be easy? Let's find out!

@nina_kali_nina That shutdown screen is giving me serious SCO OpenServer vibes.
