Key Configuration Choices

Passwordless Sudo

The wheel group does not require a password for sudo:

security.sudo.wheelNeedsPassword = false;

Auto-login

The user is automatically logged in on the first boot via getty:

services.getty = {
  autologinOnce = true;
  autologinUser = username;
};

Timezone

time.timeZone = "Europe/Rome";

D-Bus

Uses the newer dbus-broker implementation:

services.dbus.implementation = "broker";
