Having the `post-build-hook` use `nix` from the client package can lead to a deadlock in case there’s a db migration to do between both, as a `nix` command running inside the hook will run as root (and as such will bypass the daemon), so might trigger a db migration, which will get stuck trying to get a global lock on the DB (as the daemon that ran the hook already has a lock on it).
