mariadb    |
mariadb    | Installation of system tables failed!  Examine the logs in
mariadb    | /config/databases for more information.
mariadb    |
mariadb    | The problem could be conflicting information in an external
mariadb    | my.cnf files. You can ignore these by doing:
mariadb    |
mariadb    |     shell> /usr/bin/mysql_install_db --defaults-file=~/.my.cnf
mariadb    |
mariadb    | You can also try to start the mysqld daemon with:
mariadb    |
mariadb    |     shell> /usr/bin/mysqld --skip-grant-tables --general-log &
mariadb    |
mariadb    | and use the command line tool /usr/bin/mysql
mariadb    | to connect to the mysql database and look at the grant tables:
mariadb    |
mariadb    |     shell> /usr/bin/mysql -u root mysql
mariadb    |     mysql> show tables;
mariadb    |
mariadb    | Try 'mysqld --help' if you have problems with paths.  Using
mariadb    | --general-log gives you a log in /config/databases that may be helpful.
