 491 The initialization SQL script was preserved at $MYSQL_DATA_DIR/mysql-init.sql
 492
 493 Examine the logs in /var/log/mysql for more information.  You can
 494 also try to start the mysqld daemon with:
 495
 496 /usr/sbin/mysqld --skip-grant &
 497
 498 You can use the command line tool mysql to connect to the mysql
 499 database and look at the grant tables:
 500
 501 shell> mysql -u mysql mysql
 502 mysql> show tables
 503
 504 Try 'mysqld --help' if you have problems with paths. Setting on
 505 logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that
 506 may be helpful. The latest information about MySQL is available on the
 507 web at http://www.mysql.com/.
 508
 509 Please check PLD Linux ftp site for newer versions of this package.
 510
 511 Please consult the MySQL manual section: 'Problems running
 512 mysql_install_db', and the manual section that describes problems on
 513 your OS.  Another information source is the MySQL email archive.
