On some OSs for named/bind, it's simpler to have DA use some different script name, rather than trying to force the specific boot script names. Specifically on Debian, apt-get provides bind9.service, but DA would still be looking for named.service. New feature, internal default is: named_service_override=(NULL) where it's unset. To have DA call bind9.service, add this to the directadmin.conf file: named_service_override=bind9 Note, if you add named_service_override to the directadmin.conf, ensure it has a value. If it's present but blank, this means DA would call: systemctl reload .service instead of: systemctl reload bind9.service Possibility to set this as the default for new Debian 9 boxes, if that script is present.
