Right -- but that's not what distro builders use, right? I mean they do
the whole sdeb -> deb business.

In fact, to stay as faithful as possible -- I'd love to:
   1. unpack SDEB
   2. add a single patch to the set of sources
   3. repack SDEB back
   4. do whatever it is they do to go SDEB -> DEB
