Perhaps. Given you are the first person in 8 years to complain about
this (#438803) perhaps you have also an idea how as I have neither
a SELinux setup nor know what you would deem acceptable.

(truth be told, I don't even use that cron job, so I am not going to be
available for review above very trivial changes and even that…)

I guess we could use (pseudo code) "if systemd; then systemctl is-active
dbus; else pidof dbus; fi" but that would really need someone to verify
that this has the intended result (and is available in your setup).
