We are excited to announce that Arch Linux is entering into a direct collaboration with Valve. Valve is generously providing backing for two critical projects that will have a huge impact on our distribution: a build service infrastructure and a secure signing enclave. By supporting work on a freelance basis for these topics, Valve enables us to work on them without being limited solely by the free time of our volunteers.
This opportunity allows us to address some of the biggest outstanding challenges we have been facing for a while. The collaboration will speed-up the progress that would otherwise take much longer for us to achieve, and will ultimately unblock us from finally pursuing some of our planned endeavors. We are incredibly grateful for Valve to make this possible and for their explicit commitment to help and support Arch Linux.
These projects will follow our usual development and consensus-building workflows. [RFCs] will be created for any wide-ranging changes. Discussions on this mailing list as well as issue, milestone and epic planning in our GitLab will provide transparency and insight into the work. We believe this collaboration will greatly benefit Arch Linux, and are looking forward to share further development on this mailing list as work progresses.
SteamOS is based on arch, but it has major differences. The steam deck’s update mechanism is completely different from normal arch Linux.
Arch normally immediately updates to the latest version of every program. This is usually fine, but when a big bug is missed by the developers, it can cause problems.
The steam deck updates a base image that includes all the programs installed by default, and by the time it releases a lot of them aren’t the absolute newest version. When valve updates SteamOS they definitely run a lot of tests on the base image to make sure it’s stable and won’t cause any issues.
SteamOS is also an immutible distro, meaning the important parts are read only. This also means updates are done to everything at once, and if something goes wrong, it can fall back to a known good version.
Not to say arch Linux is unstable (its been better for me than Ubuntu), but SteamOS is at a completely different level. It’s effectively a completely different distro if we’re talking about stability. I think what they’re hoping is this support would allow arch to build out testing infrastructure to catch more issues and prevent them from making it to users.
This is not true though. Arch packages new program versions as soon as they can - for popular stuff this happens quickly but not everything updates quickly. And when they do publish a new package it goes to the testing repo for a short time before being promoted to the stable repos. If there is a problem with the package that they notice it will be held back until it can be solved. There is not a huge amount of testing that is done here as that is very time consuming and Arch do not have enough man power for this. But they also do not release much broken things at all. I have seen other distros like ubuntu cause far more havoc with a broken update then Arch ever has.
