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

    I have upgraded 2 of my servers to Debian Buster, and now neither one seems to be running checkarray automatically.  In addition, when I 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.

On mine it's in /etc/cron.d/mdadm

57 0 * * 0 root if [ -x /usr/share/mdadm/checkarray ] && [ $(date +\%d) -le 7 ]; then /usr/share/mdadm/checkarray --cron --all --idle --quiet; fi

dpkg -L mdadm gave me a list of files and I just checked the cron entries.

I don't run anything that recent, but Debian is Debian.
