Hi, That is because the files inside of /lib/systemd/system/ should not be changed directly (for the dpkg package management, it is not a configuration file per si) and like Kebin mentioned before, you need to override the parameters that you want using "systemctl edit pdns", which will create a override file inside of the directory /etc/systemd/system/ and will be preserved on the upgrades.
Note: The only place on the documentation that I found some mention about theses are here: https://doc.powerdns.com/authoritative/running.html#logging-to-syslog-on-systemd-based-operating-systems https://doc.powerdns.com/authoritative/performance.html#caches-memory-allocations-glibc Maybe, we should include a paragraph dedicated to it (I know, it is a systemctl setting, but it should help to clarify a bit). PS: Reply to all next time.
