... is a patch that allows a decent default mirror selection via some heuristic and a debconf question.
This is bug number 333294.
The patch is part of the git repo at http://users.alioth.debian.org/~eddyp-guest/git/pbuilder/.git. Since it uses debconf it has po-debconf support and a Romanian translation. The language should be in line with the one used in other templates, but I don't mind if anyone from Project Smith suggests some changes.
