Problem programming cron tasks in YUN

Is there an easy way to redirect the cron logs to another file and not use the system log file?

I tried modifing the cron start scritp in /etc/init.d/cron, replacing the line

ln -s /etc/crontabs /var/spool/cron/ 2>/dev/null

with

ln -s /etc/crontabs /var/spool/cron/ 2>/another/path

But the cron is still logged to the system log file.
