I verified this one with the following steps:
focal)
On a clean install:
Install bind9 and verify the named service is running:
# systemctl status named
Kill the named process
# pkill -9 named
and verify it is not automatically re-started:
Restart the service
# systemctl start named
and install the proposed fixed bind9 package in the -proposed pocket.
Verify that the named service is running. Then, kill it again
Now, the service should re-start automatically.
bionic)
Same steps as with focal, but the systemd service name is now bind9.
