Common inputs and what they affect

Recommended update workflow

1. Update inputs:

   nix flake update
   # or for a single input:
   nix flake update nixpkgs
   

2. Check what changed:

   git diff flake.lock
   

3. Dry build to catch breakage before switching:

   sudo nixos-rebuild dry-build --flake .#<hostname>
   # or for Darwin:
   sudo darwin-rebuild dry-build --flake .
   

4. Apply if build succeeds:

   ./switch.sh
   

5. Commit the lock file update:

   git add flake.lock
   git commit -m "flake: update inputs"
   

If something breaks after update

• Check if the issue is in nixpkgs vs a specific input by updating selectively
• Use --show-trace to get full error context
• Roll back to the previous lock file: git checkout flake.lock then rebuild
• Check upstream changelogs: most inputs use GitHub releases or commit history
