The nixos_flake_info metric's current_rev label was incorrectly showing the nixpkgs input revision (from /run/current-system/nixos-version) instead of the flake's own revision. Now reads from /run/current-system/configuration-revision which contains the flake's self.rev when system.configurationRevision is set in the NixOS configuration.
