Changing directory to symlink

[racke@linuxia.de (Stefan Hornburg Racke)]

The last release of my interchange Debian package has a directory:
/usr/lib/interchange/etc

Which is supposed to be empty.

The current package has a symlink:
/usr/lib/interchange/etc => /etc/interchange

But the installation keeps the directory in place.

What is the recommended solution for this problem ?
Removing the directory in the preinst script ?

Ciao
