Broken DNS after enabling TLS cert generation

After reading yesterday’s blog post about TLS cert generation Provision TLS certificates for your internal Tailscale services · Tailscale I enabled the feature. This immediately broke DNS resolution on all of my Raspberry Pi systems. /etc/resolv.conf got overwritten to only contain

# Generated by resolvconf

This is being overwritten every time the Tailscale daemon starts. Disabling the feature immediately put /etc/resolv.conf back to how it was before.

I’m using version 1.14.3.
