When I went 24.11 it exploded in some fantastic manner. None of my boot menu rollbacks worked. I spent a long ass time trying to recover the upgrade. I eventually realized it would be a lot faster to wipe, reinstall, re-import my old home and configuration.nix and I was back up.

25.05 didn’t even flinch, just worked.

Now I’m patiently waiting for postmarket to sort out LTE modems on phones before I buy an old pixel and install nixos on it :)
