The check for systemd-resolved DNSStubListener, and disabling as necessary is a new function, called just prior to start_service pihole-FTL. The check for ubuntu bionic 18.04 specifically is removed. The check if resolved is enabled is made with check_service_active() An additional check that the dnsstublistener is enabled is made. Signed-off-by: Rob Gill <rrobgill@protonmail.com>
