Probably you don't have "users.mutableUsers = false" in configuration.nix.

Without that, how would you expect root login to work after wiping
/etc/{passwd,shadow}? What should the root password be?

Apart from mutable user accounts, NixOS should recover from wiping /etc and /var
just fine. IIRC, our VM tests boot into an initially empty filesystem.

ProtectSystem seems only marginally useful for NixOS given that we already make
/nix/store read-only.
