System: Kali Linux - based on Debian (Stretch)

I noticed that the space on my root partition was continuously shrinking even though I didn't do much on the machine and it wasn't even running continuously. Then I tested a script with a lot of calls to sudo in it and noticed that var/log/auth.log was getting rather large - understandable because of the sudo calls. I took a closer look at /var/log and it looks like there haven't been any log rotations since the end of August.
According to crontab they should be rotated every day. (I'm not sure what role anacron plays here currently which may be responsible for this kind of task if the machine isn't running 24/7.)
I took a look at /etc/cron.daily/logrotate (see below) and I don't understand the purpose of the test for the existence of /run/systemd/system and the exit if it exists. The directory is empty but it exists - so unless it disappears periodically the rest of the script will never execute.
I then executed the command /usr/sbin/logrotate /etc/logrotate.conf (at the end of the script) by hand and the logs were rotated.
Okay, I may be on a completely wrong track here and would benefit from a hint in the right direction.
Here the code of /etc/cron.daily/logrotate:
Thanks.
Is cron running? Check with service cron status or service crond status. Alternatively look at cron entries in system log files. Does it show up in ps? Any error messages?
I suppose you could run this as root and see what happens. Try with the debug/trace turned on:-
What is in /etc/cron.daily/logrotate? It may be working as designed, but there are no rules being activated.
It will probably be something trivial, but infuriating. I've had 'fun' with them myself.

It does what I expected. The directory /run/systemd/system exists and hence:
I run another Debian based distribution (Raspbian) on a Raspberry Pi. That one has a shorter version of /etc/cron.daily/logrotate. It doesn't test for existence of /run/systemd/system. No problems over there:
