Comment 0 for bug 2055239

I recently started seeing the following warning messages when I run `apt update`.

$ sudo apt update
Warning: The unit file, source configuration file or drop-ins of apt-news.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Warning: The unit file, source configuration file or drop-ins of esm-cache.service changed on disk. Run 'systemctl daemon-reload' to reload units.
...

apt-news.service for example is in /lib/systemd/system/apt-news.service and it's a static file managed by the package. Does the package maintenance script call systemd related hooks to reload the config whenever the package gets updated?

$ systemctl cat apt-news.service
# /usr/lib/systemd/system/apt-news.service

$ dpkg -S /lib/systemd/system/apt-news.service
