[debian-mysql] Bug#922018: Bug#922018: mariadb-server-10.3: Logs are not in /var/lib/mysql

[Faustin Lammler]

Hi Olaf!
Since there has not been any change on the mysql_install_db.sh script
regarding this for long, I thought that such output message was normal
and that the error log would be as it says in /var/lib/mysql.

But on Debian it is not and you are right, error log goes to
/var/log/mysql/error.log.

The following permits to confirm this behavior (WARNING this delete
mariadb data):
1/ in a first terminal:
$ sudo rm -rf /var/lib/mysql/*
$ sudo -u mysql mysql_install_db

2/ in a second terminal (quickly after this last command):
$ sudo chown -R root:root /var/lib/mysql/mysql

The last command makes the creation of MariaDB Server system table fail
because mysql_install_db can't write into /var/lib/mysql/mysql and error
log goes to /var/log/mysql/error.log

I will open an issue on Jira and link this bug report to it.

Thanks again,
Faustin
