Chimera Linux
A BSD/LLVM distro from scratch
<p>Chimera Linux is a new distribution I started in the middle of 2021, after years of thinking and vague planning. After getting a bunch of real world maintenance experience managing the POWER architecture support in Void Linux, I have decided to make those ideas a reality - a distribution with the Linux kernel, but FreeBSD userland, LLVM/Clang system toolchain and core runtime, musl libc and a fair amount of custom tooling. Right now, it is a bootable system targeting a variety of CPU architectures (aarch64, ppc64le, riscv64, x86_64...) that is easily bootstrappable (and capable of building itself), testable, lightweight and fast (but still in heavy development). It uses the apk package manager (of Alpine Linux) and a completely custom source packages collection and build system written in Python, allowing for sandboxed, fully unprivileged package builds.</p>
The distribution follows a rolling release model for its simplicity and ease of release management, but without insisting on bleeding edge versions. The build tooling is capable of bringing the system up from scratch using any other musl-based distribution as a base (and without requiring any GNU components beyond currently their make implementation) - the system rebuilds itself 3 times for that purpose. Link-time optimization (specifically Clang's thin LTO) is enabled for nearly all packages. The lightweight, dependency-based, supervising 'dinit' service manager takes care of boot, and Wayland is the preferred display server. The system aims to be general purpose, not niche; a primary goal is breaking up some status quos in the Linux ecosystem and provide a truly viable alternative. It should be community driven, open, welcoming and unorthodox, without any pointless dogmatism.
In the talk I will cover my journey towards having a system capable of boot, what it took to bring up a distribution from scratch and how I dealt with various obstacles, and what I learned on the way, as well as the future of the project. Some basic Linux administration knowledge will be required from the audience, but any somewhat tech-savvy person should be able to follow.

<p>Like most developers, I'm against my will a volunteer system administrator. I take care of my personal and professional notebooks. I also maintain a powerful build server at home and a remote VPS hosting my blog. From times to times I even use a single board computer to host some services.</p> <p>A few years ago, all those machines ran different, dedicated Linux distributions: Ubuntu, ArchLinux, Debian, Raspbian, making the maintenance a nightmare. That was before diving into GNU Guix.</p> ...

<p>Flatcar Container Linux is a fully open source, minimal-footprint, secure by default and always up-to-date Linux distribution for running containers at scale. It is shipped as an image and does not include any package management. OS binaries and libraries reside on a read-only partition. This talk will briefly introduce Flatcar’s core concepts before diving into a detailed discussion on modifying, testing, and vending your own OS images using the SDK.</p>

<p>Distros have been the backbone of Linux for the past two decades, but with the advances made in cloud technology and infrastructure, they have started to become less relevant as a solution and product in itself. To be specific: Distros have been reduced from being the universal FOSS product that delivers a complete solution to the user, to a set of very nicely maintained “free beer” types of repos full of packages that make up application building blocks for custom stacks packaged with ...

<p>Imagine you're an engineer at an ODM or OEM working on a IoT product for the smarthome - from a simple thermostat to security alarms, from set top boxes to internet gateways.</p> <p>Linux is a fairly obvious choice to build these product that have greater than 128MB of RAM and storage. On resource-constrained devices, an RTOS such as Zephyr is able to even run on devices with as little as a few hundred KB of RAM and storage.</p> <p>However, the kernel is a small part of the device's software ...

<p>Maintaining a Linux distribution in a consistent and secure manner is challenging. Maintaining a one-to-one clone, can be even more challenging. Rocky Linux maintains a number of in-house tools to aid in this process and makes it as transparent and auditable as possible.</p>
