starting tor + polipo?

[pawaan]

Sorry if I have to ask this here as I still have a restricted account.
I hope someone will help me figure out the difference between case1 and case2 and which is more correct :
1- Autostart tor+polipo by putting a line in /etc/rc.conf.local that reads : pkg_scripts="tor polipo"

2- Autostart the pair by putting lines in /etc/rc.local :

#Start tor
if [ -x /usr/local/bin/tor ]; then
echo -n ' tor'
/usr/local/bin/tor
fi

#Start Polipo
if [ -x /usr/local/bin/polipo ]; then
echo -n ' polipo'
/usr/local/bin/polipo
fi
