Configuration file handling in .deb packages

[szepeviktor]

Thank you for packaging suhosin!

Please consider using ucf for the configuration file.

I think it takes one line in the source package: http://security.debian.org/debian-security/pool/updates/main/p/php5/php5_5.6.9+dfsg-0+deb8u1.debian.tar.xz

And that becomes: http://security.debian.org/debian-security/pool/updates/main/p/php5/php5-mysqlnd_5.6.9+dfsg-0+deb8u1_amd64.deb
