Answering your question: ENOSPC This is not a support forum and we're not trying to diagnose and fix someone's issue. It's just not that hard to get into trouble with NixOS and there's still a room for improvement, that's all. Reading on `nix-channel --rollback`, it should definitely help in some cases and I don't know how I missed it, maybe the docs weren't clear it's not tied to config generations or I just didn't pay enough attention.
