Hi Guillem,

while trying to check what's left to implement this, I got reminded by
this source code comment which currently IMHO very well validates
direct database usage (as you seem to have noticed, too):

    # Calling dpkg-query --control-path for every package is too slow,
    # so we cheat a little bit.

So please do so. Cloning this bug as a reminder and blocker.

Will for now upload debsums with just debsums_init removed, so at
least a bit of this issue is resolved that way.

command-line user interface and more readable output still validates
it's existence. (I really dislike that rpm format. :-)

I also haven't found an quick and easy way to just show conffiles or
non-conffiles with dpkg --verify on a quick glance. Even to grep out
the just changed ones is not that trivial.
