Bug#395853: apache2-common: removes symlinks on upgrade

Ok.

Sorry, but that's not true. /etc/apache2/conf.d/mediawiki1.7 is created by calling "ln -s" inside mediawiki1.7's postinst.
Besides, apache ain't the only package that has the ability to create files there, right?

I don't quite get your point. /etc/apache2/conf.d/mediawiki1.7 isn't provided by apache.

I just took a look at the postrm file from apache2.2-common and it seems it does not longer try to remove all symlinks in /etc/apache2/conf.d ...
I really appreciate that improvement compared to apache2-common's very greedy behavior.

Thanks,
Thomas
