When tailscaled gets started with userspace networking, it won't modify your system's network configuration. For this, it creates a noopManager for DNS management. noopManager correctly observes that there's no real OS DNS to send queries to. This leads to we completely dropping any DNS internal resolution from `dns query` This change alters this so that even without a base config we'll still allow the internal resolver to handle internal DNS queries Fixes #18354 Signed-off-by: Fernando Serboncini <fserb@tailscale.com>
