A new version of MySQL, version 5.1, is part of the openSUSE 11.2 upgrade. Once you have got the basic openSUSE 11.2 upgrade working, you will discover to your horror that MySQL is not. There are a couple of changes made to MySQL at this release.
Firstly, The MySQL socket is moved to /var/run/mysql. So you will need to edit your /etc/my.cnf file. Open this file and change all occurrences of the socket path to reflect this new path. So, for example:
socket = /var/run/mysql/mysql.sock
This will occur more than once so make sure you change them all!
