Hi Rudi, Hi all,
maybe what will help us is that we are not so much interested in
individual cornercases anyway. As a starter, we could focus on
Field::Biology packages only. Accidental de-anonymisation would mean
that one could guess who installed, say mummer, emboss, gnumed-client
and bioperl at the same time for a given version number and
architecture. I think that it is an acceptable risk, because the nature
of this information is not very valuable.
Have a nice day,
