In the 2.3.STABLE2-5 version of /etc/rc.d/init.d/squid shellscript, I
think there is a bug in find the squid spool directory. It uses this:

# determine which one is the cache_swap directory
CACHE_SWAP=`sed -e 's/#.*//g' /etc/squid/squid.conf | \
	grep cache_dir | sed -e 's/cache_dir//' | \
	awk '{ print $3 }'`

Here, the result of this is: 1024

I think this would work better:

CACHE_SWAP=`sed -e 's/#.*//g' /etc/squid/squid.conf | \
	grep cache_dir | awk '{ print $3 }'`


Result here is: /var/spool/squid

Much better for a "CACHE_SWAP" parameter.
