Seemingly you need to set an environmental variable LDB_MODULES_DISABLE_DEEPBIND The easiest way I found to do this was to create a systemd override file systemctl edit named.service Add (where it tells you to): [Service] Environment="LDB_MODULES_DISABLE_DEEPBIND=1" Save and close the file. Now start Bind9 systemctl start named.service It should work. Rowland

It did work, although I can't say I know what I did - even after reading through the bug report. ? Assuming this is eventually fixed, will the override file cause problems at that time?
