Thank you for the report Aristarkh. It is odd that this was fixed so long ago - 1:9.11.4+dfsg-1 is what the debian bug states.
That was only pushed to Debian buster in: 195 bind9 (1:9.11.4+dfsg-1) unstable; urgency=medium 196 197 [ Bernhard Schmidt ] 198 * Use systemd Type=forking to signal daemon init. 199 Thanks to Elie Roudninski (Closes: #900788) ... 209 -- Ondřej Surý <ond...@debian.org> Sat, 14 Jul 2018 12:27:56 +0000 But I don't see it on any path to Debian/sid - not in the past changelogs nor in the currently used .service files. I need to ask if this might have had an intentional reason ... or if it really was "lost again" later on. ** Changed in: bind9 (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899902 Title: systemd unit service file does not wait for bind9 to be ready To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1899902/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
