http://wiki.debian.org/DebianInstallerBuild
has a section on

 version of d-i you are building
followed by a box that looks as if it's supposed to hold text to put
in a file.  But the box is empty.

I think it's easy to guess what should be there based on the preceding
box (i.e., substitute "unstable" for "testing"), but I'm not 100%
sure.  Perhaps someone in the know could update the page.
