dnsmasq binds port 53 by default even when only proxy DHCP is needed. systemd-resolved already owns port 53 on the pxe-boot container, so dnsmasq crashes at startup. Setting port=0 disables the DNS listener entirely — pxe-boot only needs the proxy DHCP path for iPXE chainloading. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
