Great! I have just installed it here and it seems to run well. I was
thinking about making a debian package for this myself but if
you want to maintain it that's even better ;)

There's not much to be configured, the only things are:
- RAM cahce size
- disk cache size
- access restrictions

I think it would be better to wait, as this sounds as an "alpha" release.
If you release it now chances are that this will be part of the final
1.1 release. Not bad at all (would be great to have) but if you are
not sure the package is bugfree...

No, just configure it with configure -prefix=/usr/lib/squid (I think
that is the appropriate location for it) and adjust the rest of the
stuff, like log file locations, in the configuration file.

Do not hack the install part of the Makefile - this is a small package
and you can easily write the installation part (to debian-tmp/usr/lib/squid/..)
by hand in the debian.rules file.

Yeah just move the instalation part to the debain.rules file..

Another thing is that squid (the beta7) regulary crashes on our
site. Therefor it is mandatory that you run it with the RunCache
wrapper. I have put some hard work in a /etc/init.d/squid file
to get this right, so I might as well post it here so that you
don't have to reinvent the wheel. Ofcourse you'll have to adjust
the pathnames a bit. As you can see I chose /var/spool/squid for
the cahce directory, which is the "right" location IMHO.

	cd /var/spool/squid
	$DIR/RunCache < /dev/null > /dev/console 2>&1 &
	sleep 2
    # First kill the watch process, then the daemon.
    kill -9 "`pidof -o %PPID -o $$ $DIR/RunCache`" > /dev/null 2>&1

    start-stop-daemon --stop --signal 1 --quiet --exec $DIR/squid
    echo "Usage: /etc/init.d/squid {start|stop|reload}"
    exit 1

exit 0
