I have trouble to start the cron service on boot. I can start it manually with sudo /etc/init.d/cron start and crontab is working. However, this morning the service was down again, maybe the Raspberry rebootet overnight.
What is the best location to put a command to auto-start it on boot? I tried with /etc/rc.local, however, after reboot, the file had been reverted to its original state and cron had not been started.
