NixOS/nixpkgs#444829 (merged 2026-04-06) dropped the "auto" default for
fileSystems.<name>.fsType. The nixos-and-darwin-shared-homes template
only sets device for its dummy /, so nix flake check now fails with

error: The option `fileSystems."/".fsType' was accessed but has no value
defined. Try setting the option.

The template has no flake.lock and tracks nixos-unstable, so this broke
main in place — the last CI run on main (Feb 18) predates the nixpkgs
change.
