Tvheadend

My goal was to remove tvheadend logs from syslog and collect them into a separate file.

I've added this to the /etc/init.d/tvheadend script:

# Log to home folder instead of syslog
ARGS="$ARGS -l /home/hts/tvheadend.log" 

Now logs go to this new location, but somehow its level has been raised to DEBUG and it is flooded with information I do not usually need.

Also, normal level logs still go to sysleog.

What is the correct way of moving the normal level logs from syslog to a separate file?
