John Cunningham:
I hate to wade into the pool of systemd hate, but is this systemd's
fault? I noticed anacron doesn't exist on this system. Is it supposed
to anymore? Or is that one of the things that have been deprecated? If
so, how are the /etc/cron.daily jobs getting run these days?
You'll have to check the timeframe of when these changes happened with
respect to Debian 8, but a Debian 9 system does not use cron to run
anacron and various other things like phpsessionclean, nor use anacron
itself to run various further things. You'll find [ ! -d
/run/systemd/system ] in various places in Debian Linux nowadays that
turns stuff off when systemd is running, as well as reliance on the fact
that systemd ignores non-native stuff if it has native stuff of the same
name (such as anacron.timer).

Moreover, you will find the similar [ -x /usr/sbin/anacron ] in various
places to control what happens when anacron is not installed.

So bear in mind that your learned ideas about what runs what are no
longer true.
