More Fine-Grained Control of cron Output


I just moved to Leap 42.2. I’m trying to understand how to control which cron scripts mail their output to root. A pass through the options in /etc/sysconfig/cron, and a read of /usr/lib/cron/run/run-crons seems to suggest that this is an all-or-nothing thing – I can either see output from all the scripts, or none of them.

Supposing, however, that I was very interested in the nightly doings of the automatic online update, but didn’t care so much to hear from snapper once per hour. So far as I can see, there is no natural way to do that – I’m not even sure that forcing the AOU script to produce non-zero exit status would do what I want, and even if it did, I’d lose that feature every time the script is updated.

So is there some way to do this? If not, then I guess this is a feature request.
