Issue
Do I have to restart cron after changing the crontable file?
Solution
No.
From the cron man page:
...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified
But if you just want to make sure its done anyway,
sudo service cron reload
or
/etc/init.d/cron reload
