The initscript used to start mysql has been reverted to use the one shipped
by MySQL AB. This means the following changes:

 * The MYSQLD_OPTIONS="--skip-networking" option in the /etc/sysconfig/mysqld
   file has been removed, this is now set in the /etc/my.cnf file.

 * The MySQL Instance Manager is used by default, set use_mysqld_safe="1" in
   the /etc/sysconfig/mysqld file to use the old mysqld_safe script.

 * The generation of the initial system mysql database is now done when mysql
   is started from the initscript and only if the /var/lib/mysql/mysql
   directory is empty (mysql_install_db). Previousely this was quite hidden and
   silently done at (rpm) install time.

The extra MySQL-NDB server package has been merged into the MySQL-Max package 
and ndb related pieces has been split into different sub packages as done by
MySQL AB. The MySQL libraries and the MySQL-common sub package uses the
MySQL-Max build so that no functionality required by for example the NDB
parts are lost.

The MySQL-common package now ships with a default /etc/my.cnf file that is 
based on the my-medium.cnf file that comes with the source code. The
/etc/my.cnf  file is constructed at build time of this package.

To connect to the Instance Manager you need to pass the correct command line 
options like in the following examples:

  * mysql -u root --password=my_password --port=2273 --protocol=TCP
  * mysql -u root --password=my_password --socket=/var/lib/mysql/mysqlmanager.sock

Please note you also need to add a user in the /etc/mysqlmanager.passwd file and 
make sure the file is owned by the user under which the Instance Manager service 
is running under.
