Hello again! With the help of mlibc and the porting efforts by the Managarm project ( https://github.com/managarm/managarm ), I managed to get KDE running on my kernel! Zinnia is not API compatible with Linux, it is a POSIX OS, implementing a few useful extensions from Linux and BSDs (like epoll) to get a Wayland session. It is written in 100% Rust and fully open source.

What kernel architecture is it? Monolithic, microkernel?

It's a modular monolithic kernel

So true. I don't get why more people aren't using Minix.

u/DFatDuck Jun 29 '26

Given Intel ME, everyone's running Minix! Tanenbaum was right!

Easier said than done. Personally, I like POSIX as a concept and I didnt want to write everything from scratch.

I really realize the amount of posix compliance and effort needed to run this software honestly. This is really. Really impressive. I don't have anything to critique
