That means we can only report bugs and issues _after_ the final release is done. But if we build and test upstream projects as development happens, we can give feedback earlier and collectively ensure the final release has fewer regressions. That's basically the goal of our nightly repositories in postmarketOS. This talk covers how we're doing it and how you can help find bugs earlier. More information about nightly repositories (e.g. set-up) is at https://wiki.postmarketos.org/wiki/Nightly. The configuration for the builds is at https://gitlab.postmarketos.org/postmarketOS/nightly-builder.

Porting Alpine Linux to a new architecture is very straightforward, but porting it to completion, including the community repo, is no simple feat. Cross compilation, bootstrapping and weird test cases will get in your way, but there are neat tricks and tools to help you along the way.

Another person will be taking notes to try to identify "facts spoken out", and a third one just listening. After the situation and the feelings have been explained, the person listening will try to reproduce what the first person said. The goal is to show to each other how our own listening and biases interfere with communication. We will rotate with the goal of everybody having a try at each of the different positions. - Appreciation work: in order to reduce conflicts and create a welcoming environment, appreciation of our own work, and the work of others is critical. In this exercise we will work on expressing that appreciation. By working individually, we will try to identify what we do, that benefits collectively the projects we work. We will then create small groups and do the same with appreciating others' work. Eventually we will be all together and express that to the group PUBLIC CONFIRMED Workshop https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/3LW8WG/ 5053.1 (Kleiner B-IT Raum) Pablo Correa Gomez PUBLISH DMUGHP@@pretalx.postmarketos.org -DMUGHP Opening Day 2 en en 20260926T100000 20260926T100500 000500 Opening Day 2 PUBLIC CONFIRMED Talk https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/DMUGHP/ 5053.2 (Großer B-IT Raum) Oliver Smith PUBLISH VDTSXY@@pretalx.postmarketos.org -VDTSXY Rebuilding the build farm: a new package builder architecture en en 20260926T100500 20260926T110500 010000 Rebuilding the build farm: a new package builder architecture Today, we still rely on Lua scripts written over ten years ago to build all of our repositories. But Alpine has grown _a lot_ since then: we have many new architectures (one of which, riscv64, is unbelievably slow...), and a single failing test in one package still blocks the upload of all other, unrelated packages. TL;DR: the builders are very often the bottleneck of Alpine development. To meet our needs today, I'll propose some requirements I think a new architecture should have, along with an idea for what it could look like. Hopefully we can find some interested people and build the "Next Gen. Alpine-Builder"™.

An initial team was assembled, roles where created, and people that put a lot of work organically joined the team. But that contribution model has problems to scale. In 2023 the model was changed to allow people to ask to join, leading in to a considerable growth: from 8 maintainers back then to 29 nowadays. The growth, however, has resulted in greater organizational challenges, and the initial maintainers still kept greater power than everybody else. In order to change this, a legal entity has been created, with democratic governance at heart. In order to fulfill our mission, more changes are needed, and we expect to do it in a democratic and respectful way with our ideals.

As such, operating systems like Android have undertaken serious efforts to harden themselves against attackers. At the heart of Android's hardening efforts is SELinux, an implementation of mandatory access control (MAC). In this presentation, we will explain what MAC is and showcase the benefits of SELinux. We will briefly compare it to AppArmor and then look into the history of MAC in postmarketOS and the technical challenges that come with integrating SELinux into Alpine Linux and postmarketOS. Thanks to the work done by members of the postmarketOS SELinux effort, we will even showcase a demo at the end!

When the Steam Frame was announced, I asked my self will it run postmarketOS or another distro? I had a look a https://wiki.postmarketos.org/wiki/Category:Headset and found out that none of the devices fits my use case. So I started building my own one, based on HadesVR. Since I know that my OnePlus 6 is alreay supported by both Godot Native Mobile VR and postmarketOS, I think that is a good startingpoint. My next plan is to get Godot Engine running on a postmarketOS phone, once that works start porting Monado. For 6DoF Tracking, I will be using libsurvive (an Open Source Lighthouse Tracking library) with a Vive Tracker. My future plans include testing VR on more postmarketOS devices, as well as porting games including Overte and the Luanti OpenXR branch. I will also build my own libsurvive compatible trackers using an IMU, an RP2040 and TS4231 sensors. Wireless trackers will use the Nordic Semiconductor nRF52840, which is also used by Smol Slime Trackers and the Crazyradio 2.0.
