 484 The initialization SQL script was preserved at $MYSQL_DATA_DIR/mysql-init.sql
 485
 486 Examine the logs in /var/log/mysql for more information.  You can
 487 also try to start the mysqld daemon with:
 488
 489 /usr/sbin/mysqld --skip-grant &
 490
 491 You can use the command line tool mysql to connect to the mysql
 492 database and look at the grant tables:
 493
 494 shell> mysql -u mysql mysql
 495 mysql> show tables
 496
 497 Try 'mysqld --help' if you have problems with paths. Setting on
 498 logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that
 499 may be helpful. The latest information about MySQL is available on the
 500 web at http://www.mysql.com/.
 501
 502 Please check PLD Linux ftp site for newer versions of this package.
 503
 504 Please consult the MySQL manual section: 'Problems running
 505 mysql_install_db', and the manual section that describes problems on
 506 your OS.  Another information source is the MySQL email archive.
