MichaelAblassmeier: dbconfig-common is great, i use it for zabbix-server-mysql. Implementing it was a matter of minutes (even tho Documentation can be a bit improved, though). It simplifies handling of databases from packages (like, creating all needed users/databases, handling database upgrades on new upstream versions) very well. Sean is very responsible when it comes to bugreports and suggestions, thanks for that!
NathanaelNerode: Obvious winner, it even made it into policy, didn't it? Now we have to convince people not to use it to ask silly questions.
