Ok, thanks for the additional info. So this rules out
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1094636#10


What you could do then, is to generate the list of known hashes 
on-the-fly by taking "hostname -i" into account. Instead of hard-coding 
the hashsums, you generate them in preinst in exactly the same way as 
previous versions did.

Does that make sense?
