A disabled nscd breaks nss module loading on NixOS, and systemd without its nss modules doesn't really work either - instead of silently disabling its nss modules if nscd is disabled, let the assertion in nsswitch handle this.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at https://nixos.org/nixos and in the manual in doc/manual.
