currently the build script doesn't maintain a "clean" chroot for local debian builds because it never removes unused packages from old builds. So I wrote a small patch which should fix it. The code is similar to the existing rpm implementation except that it is a bit more difficult to get a "unique" id from a package (for rpm the buildtime is used but debian doesn't provide something like that (or at least I didn't find anything:) )). I just realized that we could also use the mtime of the "md5sums" file (for an installed package we can use /var/lib/dpkg/info/<pkg>.md5sums) as a buildtime indicator. If we use this approach it would really simplify the code - the only "problem" is that this check will fail if a package has no files (so an already installed package might be installed again).
I just implemented this approach but it doesn't seem to be "practible" because there's quite a number of packages which don't ship a "md5sums" file (in my test chroot 28 out of 127 packages were reinstalled due to the missing md5sums file (but I don't know if these numbers are representable)). So if we want to do it "correctly" we probably need to do something like my first patch does (I know it's ugly but it works:) ).
