Don't touch the init script. It would get overridden by a future package
update.

/etc/my.cnf is the configuration file where you add all the desired
tuning options. It will not be touched by an update.

For your help the mysql-server package ships with example configurations
for different setups:

/usr/share/mysql/*.cnf
