Android Tailscale clients register with hostname "localhost", which breaks DNS resolution when machines have search domains (e.g. search .kpv.vpn) causing localhost to resolve to the Android device's tailnet IP instead of 127.0.0.1. Adds an opt-in CronJob that periodically checks for nodes with forbidden hostnames and renames them to <name>-<node-id> (e.g. localhost-12345). Includes independent RBAC (works without the in-cluster client enabled). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
This is a workaround that will be removed once Headscale gains native support for rejecting or renaming nodes with forbidden hostnames. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
