LabCraft: a hands-on Nix course built around real failures

Quick follow-up from the LabCraft intro thread: one Nix-specific course-design question felt worth splitting into its own topic rather than burying here.

I’m asking whether beginner-facing LabCraft material should teach the classic CLI first (nix-shell, nix-env, nix-store) or the modern CLI first (nix shell, nix search, nix path-info, flakes enabled), with the other shown as translation context.

New thread here.

I’d especially value feedback from people who have taught or onboarded new Nix users.
