YPS 2024.12 - Sergio Prado - Honey, I shrunk the rootfs!

In this session, we dive deep into the process of crafting the smallest possible root filesystem using the Yocto Project.

In the world of embedded systems, optimizing for size, performance, and efficiency is crucial. The Yocto Project offers a powerful framework for building custom Linux distributions tailored for embedded environments. But how small can we really go? This talk will explore strategies to create the tiniest possible root filesystem, perfect for resource-constrained devices. Whether you're building for IoT devices, minimal containers, or deeply embedded platforms, this session will arm you with practical tips and tricks to shrink your root filesystem to the bare minimum without sacrificing essential functionality. Along the way, we’ll also delve into the inner workings of root filesystem image generation in OpenEmbedded and the Yocto Project.
