 BigBabyThor | So if a nix flake update updates to a broken system, how would you revert to a previous lockfile? Would you just have to make a backup of the lockfile before you run the update? Or could you sort of source those from a previous generation

solution 1: always git your lockfile
solution 2: pick some previous version known to work | 04:01:27 |
