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.

Holy shit
acknowledgement??Steam support two weeks ago be like:
Reading the announcement, this won’t be changed. Steam on Arch is still not supported.
Not officially supported but it works just as well and might be more well documented than Ubuntu, regarding support and issues
Gaming in Arch Linux through Steam has been incredibly smooth for me.
Same. I have had a couple of hiccups but nothing more than I did gaming on Windows. Overall my transition to Linux, especially for gaming, has gone exceptionally smooth.
I run Steam on Arch as a Flatpak (because it tends to be pretty messy with dependencies so it’s nice to have it all contained in one place) and it’s always worked perfectly well for me too.
They should support Flatpak.
Completely fair. They have specific distro they support, and their staff is trained for. Also this seems like you’ve got some OS level issues independent from steam…
If Windows or MacOs had a variety of distributions, Valve would similarly limit support to a practicable number.
I’ve had weird issues with missing codecs in Windows N variants. It definitely happens
Maybe that bug report was the motivation for the collaboration! Or maybe the level 1 support aren’t aware of unannounced business decisions.
The Steamdeck was motivation for the collaboration - since it is based on Arch Linux. But as a desktop client they only support ubuntu officially which makes level 1 tech support easier as supporting every distro can be very complex.
Working in open-source, frequent issues do end up being future feature requests.
They support Unity???
Unity desktop: Ubuntu’s DE
Yes I know, and no they use GNOME with a few extensions, they have abandoned Unity since quite a while, I would wonder if there still was a supported LTS with Unity.
There is a Unity variant that’s still maintained
I am curious as per the secure enclave part. Does it mean that they will be signing binaries? Does it mean that we will get secure boot support without self signing? Does it mean that there will be a signing system for the anticheats???
Package signing is used to make sure you only get packages from sources you trust.
Every Linux distro does it and it’s why if you add a new source for packages you get asked to accept a key signature.For a long time, the keys used for signing were just files on disk, and you protected them by protecting the server they were on, but they were technically able to be stolen and used to sign malicious packages.
Some advanced in chip design and cost reductions later, we now have what is often called a “secure enclave”, “trusted platform module”, or a general provider for a non-exportable key.
It’s a little chip that holds or manages a cryptographic key such that it can’t (or is exceptionally difficult) to get the signing key off the chip or extract it, making it nearly impossible to steal the key without actually physically stealing the server, which is much easier to prevent by putting it in a room with doors, and impossible to do without detection, making a forged package vastly less likely.There are services that exist that provide the infrastructure needed to do this, but they cost money and it takes time and money to build it into your system in a way that’s reliable and doesn’t lock you to a vendor if you ever need to switch for whatever reason.
So I believe this is valve picking up the bill to move archs package infrastructure security up to the top tier.
It was fine before, but that upgrade is expensive for a volunteer and donation based project and cheap for a high profile company that might legitimately be worried about their use of arch on physical hardware increasing the threat interest.That sounds awesome. I never understood how a TPM can figure out if an attacker can get the keys if the tpm is on the same machine. Does it check independently the signature of the application that asked for the keys?
Depends on the vendor for the specifics. In general, they don’t protect against an attacker who has gained persistent privileged access to the machine, only against theft.
Since the key either can’t leave the tpm or is useless without it (some tpms have one key that it can never return, and will generate a new key and return it encrypted with it’s internal key. This means you get protection but don’t need to worry about storage on the chip), the attacker needs to remain undetected on the server as long as they want to use it, which is difficult for anyone less sophisticated than an advanced persistent threat.The Apple system, to its credit, does a degree of user and application validation to use the keys. Generally good for security, but it makes it so if you want to share a key between users you probably won’t be using the secure enclave.
Most of the trust checks end up being the tpm proving itself to the remote service that’s checking the service. For example, when you use your phones biometrics to log into a website, part of that handshake is the tpm on the phone proving that it’s made by a company to a spec validated by the standards to be secure in the way it’s claiming.
So Arch now is a corporate distribution?
