Yeah, I know about NisOS and the new junkies/fans of that distro.
I have: 1 Thinkpad + 1 GrapheneOS = I don't need to keep in sync multiple PCs/laptops.
The second thing - my FrankenArch doesn't break. Don't the screenshot you can see the amount of days I use Arch, and nothing has broken since then.
But yeah, as soon I'm tired of Arch (it may happen, because it's boring and nothing breaks), I will try NixOS.
