#NixOS update after sleeping for one month on host floyd (lenovo x260) takes 1 hour and 15 minutes (despite new 2TB SSD). During that, the device is almost non-responsive for anything else.
Host jackson (with even a slightly larger setup) probably would need 5-10 minutes maximum (lenovo t490). (I do weekly updates there.)
Didn't had that update "performance" while using Xubuntu LTS before. 🤔
@publicvoit i installed nix-output-manager which really helped with this, cause I was able to see which packages were taking a long time to build. in my case they were ones I was pulling from unstable or from github flakes - switching to stable packages from nixpkgs sped things up loads. ymmv, but it might be worth a shot - https://github.com/maralorn/nix-output-monitor
@stefan I'm using https://github.com/viperML/nh which is using that tool as well. Unfortunately, its screen output colors are broken and therefore, I actually can't identify the important yellow lines at all. 🤷
However, I had to wait maybe half an hour before that part of the upgrade even started.
