You don't need to add any config files if you are using squid-deb-proxy.
Just install it on one box (with lots of extra disk space and a good
network connection!) and then install squid-deb-proxy-client on all of
your machines on the same LAN that need to use it, and it installs the
appropriate apt-conf.d file to pick it up from the avahi publish.
