The @nixos_org integration tests have always been a fantastic tool - We just made them even faster and much simpler to run! 🚀 By adding a new lightweight container backend to the test driver, you can now run your suites on standard, non-KVM hosts. 👇
Here is what the new container backend brings to your NixOS workflow:

The NixOS appliance series continues: After we successfully minimized our image in part 2, it's time for the next step: Enable automatic Over-The-Air (OTA) updates!
Part 3 is now live! This article shows you how to build a truly robust, self-updating system using NixOS. We dive deep into:
🔹 Creating immutable A/B system partitions with systemd-repart.
🔹 Preparing the update packages.

Working on the @nixos_org test driver at #OceanSprint this week has been great. A few notable improvements for your test suites:
SSH Backdoors: Migrated to vhost-device-vsock. No more CID conflicts or extra sandbox paths needed.
Fail-Fast: qemu.forceAccel lets you force KVM/HVF and fail immediately if it’s unavailable.
Log Hygiene: The driver now uses proper log levels instead of just dumping ever

So you created your favorite product system image, minimized it, tested its systemd-sysupdate over-the-air update capabilities, your CI automatically tests it in sandboxed virtual networks, and you are happy with it. Now your carefully engineered product wants to be deployed to a smaller embedded system without hassle? Maybe even from your Mac?

Just learned today that you can completely drop `treefmt-nix` (and all the follows lines if you have that) from your flake inputs. This is amazing:
It seems like @Codeberg is sometimes really slow because they have some load problems, but most of the time i did not experience that.
How @forgejo is so much fun to use, mostly because of 2 things for me:
- it's really snappy. No waiting most of the time as it's normal on github and gitlab.
