It's not so much what as 'how much'. Doing this is relatively easy. If we
are just talking about stdout and stderr, that would be easy as well.

When explained this way, I can understand the pro's of using dpkg to do
the logging. As it was explained before, I wasn't sure of the benefits
from it.
Getting dpkg to call dpkg-logger is a viable solution using the scripts
stdout and stderr descriptors. It would also allow dpkg to fill in the
blank for the package name on the dpkg-logger command line args. And your
right that the plus side is not having to modify the package scripts
(except that maintainers may want to add stderr as an output option for
certain messages) and it would wipe out dpkg logging and package logging
in one bang.
The only draw back I see to this is that it would require modifying dpkg
code. I'll look into this and see what Ian thinks of the patch as well as
posting it here.
