Having the mdcheck script is not use if is never run. This patch adds systemd unit files so that it can easily be run on the first Sunday of each month for 6 hours, then on every subsequent morning until the check is finished. The units still need to be enabled with systemctl enable mdcheck_start.timer The timer will only actually be started when an array which might need it becomes active.
