Replace the single-quoted value `''` with the copied value. It should have similar output as the previous mkpasswd.
### passwordFile
### hashedPasswordFile
Note that the hash is still world-readable. A more secure option is to use `users.<name>.passwordFile`. Save the hash into a file (e.g. "/etc/nixos/nixos.password") and restricts the file to be readable by root only (`chown root:root` and `chmod 600`).

You might be wondering why not just `passwordFile` during installation. The issue is that, in the live CD environment, the "/etc/" folder refers to the live CD's not the actual one which is located in "/mnt/etc/". I mean, you _could_ try "/mnt/etc/nixos/nixos.password", but remember to update the option after reboot otherwise you would get locked out. "./nixos.password" value doesn't work because `passwordFile` option doesn't support relative path, it must be a full path. Hence, I have to use `hashedPassword` during the initial setup and then switch to `passwordFile`. Remember to remove the `hashedPassword` option once you have set up `passwordFile`.
