In the previous article we walked through how to set up our very own Nix binary cache.

It’s great being able to run attic push system /run/current-system on whichever machine we are currently using, but the the chances are that if you use Nix to manage your system configurations, you have a system configuration monorepo, and depending on how many machines and architectures you are targeting, it can quickly become tiresome to manually push to the cache from each of them.

I recently starting using Yubikeys both to store passkeys which allow me to do passwordless logins to websites like GitHub, and to SSH into remote servers with FIDO2.

I have a number of machines at home, but I spend the majority of my time using a Windows 11 desktop computer running NixOS on WSL2 (in the past I’ve described Windows 11 + my tiling window manager komorebi as the “desktop environment” on top of my NixOS WSL2 shell).
