Bottlerocket OS
An operating system designed for hosting containers
Bottlerocket is a free and open-source Linux-based operating system meant for hosting containers. Bottlerocket focuses on security and maintainability, providing a reliable, consistent, and safe platform for container-based workloads. This is a reflection of what we've learned building operating systems and services at Amazon. The base operating system has just what you need to run containers reliably, and is built with standard open-source components. Bottlerocket-specific additions focus on reliable updates and on the API. Instead of making configuration changes manually, you can change settings with an API call, and these changes are automatically migrated through updates. Hosting containers doesn’t require much from an operating system and hosting containers is all Bottlerocket aims to do. Many of the packages, tools, interpreters, and dependencies installed by default in general-purpose Linux distributions are simply not needed to only host containers. -

Alfheim ISE
A CC0 operating system written from scratch in Rust.
"Software is best, which imposes no restrictions" A full Creative Commons 0 licensed operating system (or rather a completely free operating system to do what you will with it) written in Rust, built for an AMD64 environment. We will not support x86 architectures. The future looks promising, once we get a full AMD64 environment stable, we will also work on an ARM64 environment and a quantum computer environment. Our goal is an in place replacement to our current everyday systems (The creators use Linux daily, and support Windows and MacOS systems at work) that doesn't have all of the bloated crapware that is invading all operating systems nowadays (just look at systemd). We will build our complete environment in Rust. All of our base apps will be in Rust, and we will build a Gnu toolchain replacement so if you would like 'x' open source software to be installed on the system it can. As such this will be a fully Integrated System Environment. -
