+To start mysqld at boot time you have to copy
+support-files/mysql.server to the right place for your system
+
+PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
+To do so, start the server, then issue the following commands:
+/usr/bin/mysqladmin -u root password 'new-password'
+/usr/bin/mysqladmin -u root -h sgn02 password 'new-password'
+
+Alternatively you can run:
+/usr/bin/mysql_secure_installation
+
+which will also give you the option of removing the test
+databases and anonymous user created by default.  This is
+strongly recommended for production servers.
+
+See the manual for more instructions.
+
+You can start the MySQL daemon with:
+cd /usr ; /usr/bin/mysqld_safe &
+
+You can test the MySQL daemon with mysql-test-run.pl
+cd mysql-test ; perl mysql-test-run.pl
+
+Please report any problems with the /usr/bin/mysqlbug script!
