Install Hints

MySQL will only install if you have a NON-NUMERIC hostname that is resolvable vi
"10.0.0.1 myhostname".

A new mysql user "debian-sys-maint" will be created. This mysql account is used

Please remember to set a PASSWORD for the MySQL root user! If you use a /root/.m
/usr/share/doc/mysql-server/README.Debian for more information.

<Ok>
