Afaik dpkg does not remember what is a link to and what is a directory
in a package so it can't properly track that change in the package and
can't differentiate it from the admin moving and linking a
directory. That is the bad news.
Now the good news. I think moving and linking directories could be
forbidden and be replaced by moving and mount --bind. It avoids the
pritfalls of symlinked dirs completly and provides all the features.

I think post etch this could be a good idea. But someone has to dig
into dpkg to implement it.
