Is there seriously no one here who knows how checkarray was 
launched in previous versions?

run checkarray manually, it isn't sending update emails on the status 
of the job.  Actually, I have never been able to figure out how 
checkarray runs.  One my older servers, there doesn't seem to be 
anything in /etc/crontab, /etc/cron.monthly, /etc/init.d/, 
/etc/mdadm/mdadm.conf, or /lib/systemd/system/ that would run checkarray.
