Sorry for the delay, been busy with the prep for school year to start, and the notification email of reply got buried.

One job only runs this command nightly.

rm -f /opt/carsi/spool/*/.spllock

which cleans up some files that our ERP sometime doesn't auto-delete. I can't post the actual job per policy here. but is a basic few line job.

You mentions systemd, I don't know much about that. On HP-UX we use to be able to set the cron log level, and I read some Linux have similar settings. It seems suse doesn't.
