There's no special logic around it in MySQL 5.6 and no changes in
chown is done if user=xxx is specified on the command line or in the
my.cnf file. And if chown fails, you'll see the error message and
mysql_install_db will abort. Both in MySQL and MariaDB.
What is different, though, in MySQL mysql_install_db will only read
the [mysqld] section in my.cnf, while in MariaDB it will read all
sections that the server will (for me it's: mysqld server mysqld-10.1
mariadb mariadb-10.1 client-server galera). So if one of those sections
in your my.cnf contains "user=mysql", then MariaDB's mysql_install_db
will see it, but MySQL's mysql_install_db won't.
