Instead of changing the dnsmasq configuration, we replace gravity.list and black.list by empty files for disabling. When pihole-FTL receives SIGHUP, it will clear its cache and reload all configured lists. If the files are empty, blocking will be disabled as no content to be blocked will be imported.
