I use xen instances and that changes nothing at all.

1. My ~/src is mounted inside the build environment so I don't have to
copy the source around all the time

2. building generates the diff.gz and dsc file

Note: you can't generally even build source outside the build
environment as any Build-Depends could be required

Note 2: Building source can already add huge amount of spam to the

So when you "debdiff debian.dsc local.dsc" you get all the changes
even the autogenerated stuff. Real pain to have 100k line diff for a 5
