Cowbuilder and Tor
You've installed apt-transport-tor to help prevent targeted attacks on your system. Great! Now you want to build Debian packages using cowbuilder, and you notice these are still using plain HTTP. If you're willing to fetch the first few packages without using apt-transport-tor, this is as easy as: Add 'EXTRAPACKAGES="apt-transport-tor"' to your pbuilderrc. Run 'cowbuilder --update' Set 'MIRRORSITE=tor+http://http.debian.net/debian' in pbuilderrc. Run 'cowbuilder --update' again. Now any future builds should fetch build-dependencies over Tor....
