I am also seeing this -- not just in the syslog, but also in the terminal, in
extra noticeable bold font, every time apt touches systemd.
To make things even more confusing, there's a whole host of reports of this as
can be seen at <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1104641> and
all the duplicates merged into it, that are all closed as "wontfix" without a
single word of explanation. Surely, a warning indicating a possible
misconfiguration is worth tracking in some form; a bug-free system would not
show any such warning.
Kind regards,
Ralf
