Deleting emails will not save the planet

A while ago I saw a post on LinkedIn that piqued my interest, not because it was any good, but because it was impressively wrong. It claimed that, to quote, “if every email user deleted just 10 emails, it would save enough electricity to power millions of households each year”. This is not only wrong, it is obviously wrong. In this post, I’d like to dive into why it’s wrong, how one might come to think it’s right, and perhaps what better message you could put out there to save the planet.

SSH CA with device and identity attestation: ssh-tpm-ca-authority

The past year I have been hacking around on tools utilizing TPMs, and one of the features I have been interested to learn more about is the device attestation features. After being a bit inspired by some ideas from people at work, the hackerspace and toots on mastodon, I figure out a SSH certificate authority would be a cool small project to hack on. Last year I wrote an SSH agent with TPM bound keys so this would nicely fit into the existing tooling.

Reproducible Arch images with mkosi

Manual intervention for pacman 7.0.0 and local repositories required

With the release of version 7.0.0 pacman has added support for downloading packages as a separate user with dropped privileges.

For users with local repos however this might imply that the download user does not have access to the files in question, which can be fixed by assigning the files and folder to the alpm group and ensuring the executable bit (+x) is set on the folders in question.

$ chown :alpm -R /path/to/local/repo

Remember to merge the .pacnew files to apply the new default.

Pacman also introduced a change to improve checksum stability for git repos that utilize .gitattributes files. This might require a one-time checksum change for PKGBUILDs that use git sources.

Optimized cloud-init template on Proxmox

There are already quite a few resources out there demonstrating how to create a cloud-init enabled VM template in Proxmox. Here are the ones I mainly used to discover the topic, and which I suggest you go through because what follows depends on them:

Proxmox [wiki](https://pve.proxmox.com/wiki/Cloud-Init_Support) and [official documentation](https://pve.proxmox.com/pve-docs/chapter-qm.html#qm_cloud_init) on Cloud-Init support
Perfect Proxmox Template with Cloud Image and Cloud Init (YouTube, Techno Tim 2022-03)

What those and many similar resources give are step-by-step instructions divided in as many commands to facilitate understanding. What I haven’t seen so far though, is an all-in-one, optimized command to do the same thing, …

Providing a license for package sources

Arch Linux hasn't had a license for any package sources (such as PKGBUILD files) in the past, which is potentially problematic. Providing a license will preempt that uncertainty.

In RFC 40 we agreed to change all package sources to be licensed under the very liberal 0BSD license. This change will not limit what you can do with package sources. Check out the RFC for more on the rationale and prior discussion.

Before we make this change, we will provide contributors with a way to voice any objections they might have. Starting on 2024-11-19, over the course of a week, contributors will receive a single notification email listing all their contributions.

If you receive an email and agree to this change, there is no action required from your side.
If you do not agree, please reply to the email and we'll find a solution together.

If you contributed to Arch Linux packages before but didn't receive an email, please contact us at [email protected].

Dear blog. This post is inspired by an old friend of mine who has been writing these for the past few years. I meant to do this for a while now, but ended up not preparing anything, so this post is me writing it from memory. There’s likely stuff I forgot, me being gentle with myself I’ll probably just permit myself to complete this list the next couple of days.

Critical rsync security release 3.4.0

We'd like to raise awareness about the rsync security release version 3.4.0-1 as described in our advisory ASA-202501-1.

An attacker only requires anonymous read access to a vulnerable rsync server, such as a public mirror, to execute arbitrary code on the machine the server is running on. Additionally, attackers can take control of an affected server and read/write arbitrary files of any connected client. Sensitive data can be extracted, such as OpenPGP and SSH keys, and malicious code can be executed by overwriting files such as ~/.bashrc or ~/.popt.

We highly advise anyone who runs an rsync daemon or client prior to version 3.4.0-1 to upgrade and reboot their systems immediately. As Arch Linux mirrors are mostly synchronized using rsync, we highly advise any mirror administrator to act immediately, even though the hosted package files themselves are cryptographically signed.

All infrastructure servers and mirrors maintained by Arch Linux have already been updated.

Glibc 2.41 corrupting Discord installation

We plan to move glibc and its friends to stable later today, Feb 3. After installing the update, the Discord client will show a red warning that the installation is corrupt.

This issue has been fixed in the Discord canary build. If you rely on audio connectivity, please use the canary build, login via browser or the flatpak version until the fix hits the stable Discord release.

There have been no reports that (written) chat connectivity is affected.

Infrastructure as Advent of Code

In the cold of December we have but one thing to keep us warm: our laptops, trying to solve Advent of Code puzzles with inefficient algorithms. This year, 2024, is the tenth edition, and the puzzles are filled with more Easter eggs than ever before. Unfortunately, I’m not interested in Easter eggs, or solving the puzzles. I am a DevOps engineer, and I’m going to apply Infrastructure as Code principles to Advent of Code.

Cleaning up old repositories

Around two years ago, we've merged the [community] repository into [extra] as part of the git migration. In order to not break user setups, we kept these repositories around in an unused and empty state. We're going to clean up these old repositories on 2025-03-01.

On systems where /etc/pacman.conf still references the old [community] repository, pacman -Sy will return an error on trying to sync repository metadata.

The following deprecated repositories will be removed: [community], [community-testing], [testing], [testing-debug], [staging], [staging-debug].

Please make sure to remove all use of the aforementioned repositories from your /etc/pacman.conf (for which a .pacnew was shipped with pacman>=6.0.2-7)!

Rust edition 2024 annotated

Last Thursday Rust 1.85 was released, and with it, edition 2024 has dropped. The new edition is significantly larger than the two editions that preceded it, and contains many small but significant quality of life improvements to the language. In this post, I’d like to explain what an edition is, and summarize all the changes that were made to the language I love. If you need the details, I recommend reading the edition guide, but for a general overview, read on.

Valkey to replace Redis in the [extra] Repository

Valkey, a high-performance key/value datastore, will be replacing redis in the [extra\] repository. This change is due to Redis modifying its license from BSD-3-Clause to RSALv2 and SSPLv1 on March 20th, 2024.

Arch Linux Package Maintainers intend to support the availability of the redis package for roughly 14 days from the day of this post, to enable a smooth transition to valkey. After the 14 day transition period has ended, the redis package will be moved to the AUR. Also, from this point forward, the redis package will not receive any additional updates and should be considered deprecated until it is removed.

Users are recommended to begin transitioning their use of Redis to Valkey as soon as possible to avoid possible complications after the 14 day transition window closes.

Easter hack: terraform-provider-openwrt

April is usualy tax season for most people in Norway, and as I got some “money back on the skætt” I wound up purchasing an OpenWrt One to replace my 13-14 year old Asus router. I’ve been meaning to learn a bit more about networking in general and getting an OpenWrt router seemed like a fun project. Last year I bought a Beryl AX from GL-Inet as I was travelling for a few weeks.

Transition to the new WoW64 wine and wine-staging

We are transitioning the wine and wine-staging package to a pure wow64 build. This change removes the dependency on the multilib repository for wine and wine-staging.

The main reason for this is to align with upstream Wine development, which simplifies packaging and the dependency chain.

Potential Issues:

OpenGL Performance: A known limitation of the new WoW64 mode is reduced performance for 32-bit applications that use OpenGL directly
Breaking Changes: Existing 32-bit prefixes needs to be recreated

If you are facing issues with 32 bit prefixes, please recreate these and reinstall the application.
