If multiple "cache_dir" tags are present in
/etc/squid.conf, the init script used to control squid
(/etc/rc.d/init.d/squid) breaks down due to the binary test
of $CACHE_DIR. This assumes one cache_dir only.
In fact, this test needs to be a for... loop over all the
values of CACHE_DIR, and run the "init_cache_dir" mode if
*any* of them are invalid.

fixed in the next squid release (2.1.PATCH2-2...)
