Varnish
On FreeBSD, remember to copy the default configuration file to a new file and use the new file.Upgrading varnish will overwrite the default configuration file. And no, varnish does not come with a varnish.conf.dist - unfortunately.
Upon contacting the port maintainer I got a rude reply that the above is default for a lot of ports, yet it is the first time in 15 years of FreeBSD ports I have seen it. And I'm not shy about using ports - I actually prefer ports over packages.
