At our new company we have a dedicated MySQL database machine and we use OTRS for ticketing.
The thing is when you use the packages provided by otrs, you end up installing mysql-server on the otrs-machine. And that's just what I didn't want to do. So instead of just complaining I edited the spec files, the rcotrs-config files and rebuilded the rpm.
Now you don't need to install mysql-server anymore and the otrs init file isn't checking anymore for a running database. However the otrs init still tests the connection to the database. Just what we want.
