| Sounds like you want a dpkg mode where you can pre-depend on a prior
| version of your own package, and _not_ delete files that are shipped by
| the base package that are not shipped by the 'delta deb'.  Because of
| this pre-dependency, you would not be able to install this deb as a new
| install, it would have to be an upgrade.

Something like:

Package: huge-dataset
Depends: huge-dataset-base-2010-09-01, huge-dataset-patch-2010-09-10, huge-dataset-patch-2010-09-20, huge-dataset-patch-2010-09-30

And then have huge-dataset set up the data set and patch it as new
versions are installed?
