Now the SIM (System Integrity Monitor) has been configured we will add a cron.
./setup -c
If it says "Removed SIM cronjob." then you must type it again.
./setup -c

You will now see
Installed SIM cronjob.
This means SIM has been installed and the crontab will run to check the service status, it will email you if anything goes wrong.
