I only want to mess with it once and be done with it. Why not look at picobsd (in ports). It's a script that you run on your FreeBSD box which produces a minimal system on small media (single floppy, bootable CD, CF disc etc), and is ideally suited for running routers, firewalls, etc. You customise it for your exact requirements. It boots up and runs from RAMdisc - no hard disc required. Problems? Reboot and it's clean again.. Obviously the less you have on any externally exposed machine, the less security risk it poses. Since you can use pretty much any crap hardware to run as a router/firewall, find an old P1 (or worse) somewhere, and hide the decent machine you would need for squid internally, and put that, cvsup, etc on that, where it's safer. To upgrade the router, you just re-run the script to create a new floppy, disc image, etc. [any technical questions on picobsd best addressed to freebsd-small mailing list].
