maestro
Lightweight, Linux-compatible kernel, written in Rust to leverage the safety of the typesystem. Aiming to remove as much legacy as possible while supporting most usecases (by maestro-os)

Project mention: Introducing LlamaStash: a zero-overhead, terminal-native llama.cpp launcher | dev.to | 2026-06-02
Building LlamaStash brought me back to a lot of that, but the ground has shifted. ratatui (the maintained fork of tui-rs) is a real, polished framework now. tokio makes async daemons boring in a good way. hyper gives you a respectable HTTP server in a few hundred lines. crossterm handles the cross-platform terminal mess. sysinfo covers host metrics. The pieces are all there and you have LLMs to help you speed up everything to 10x.

httm
Interactive, file-level Time Machine-like tool for ZFS/btrfs/nilfs2 (and even Time Machine and Restic backups!)
-
-
aero
Aero is a new modern, experimental, UNIX-like operating system following the monolithic kernel design. Supporting modern PC features such as long mode, 5-level paging, and SMP (multicore), to name a few.

scriptisto
A language-agnostic "shebang interpreter" that enables you to write scripts in compiled languages.
Project mention: "Stop Designing Languages. Write Libraries Instead." (2016) | news.ycombinator.com | 2026-01-07You can use various programming languages with shebangs.
C#: https://devblogs.microsoft.com/dotnet/announcing-dotnet-run-...
Java: https://dev.to/toliyansky/scripting-with-java-3i9k
Go: https://golangcookbook.com/chapters/running/shebang/
https://github.com/igor-petruk/scriptisto will let you generate shebang scripts for pretty much any language

fcp
A significantly faster alternative to the classic Unix cp(1) command, copying large files and directories in a fraction of the time.

linux-0.11-rs
Linux 0.11 rewritten in idiomatic Rust: kernel, std-style user library, and 60+ coreutils — boots on i386 in QEMU.
Project mention: Linux 0.11 rewritten in idiomatic Rust, boots in QEMU | news.ycombinator.com | 2026-07-13For fun, I decided to take a look at a random syscall: fork.
* https://github.com/yuan-xy/Linux-0.11/blob/master/kernel/for...
* https://github.com/Poseidon-fan/linux-0.11-rs/blob/420152fdf...
The Rust is slightly shorter, though it also isn't organized in exactly the same way.
Maybe I got lucky, but I would expect that it's more of what other people said: this repository includes far more than the kernel.
