# App + dnsmasq in one container. Use this image for running dnsmasq (and the UI) in Docker.
# Both run as root; file permissions work because config dirs are in the container.
# For dnsmasq on the host, use the self-contained publish (scripts/publish-self-contained.sh)
# or run the app on the host; see DnsmasqOptions XML doc for permissions and ReloadCommand scope.
