We've been performing MySQL 5.6 to 5.7 upgrades for some of our clients.
In MySQL 5.6 the --log-error is passed on the command line when MySQL is started. With MySQL 5.7 it's missing. I can see in the /etc/my.cnf.rpmnew file that there is a log-error=/var/log/mysqld.log set, but the upgrade is not merging that into /etc/my.cnf so it's not getting set.
On servers that just had MySQL 5.7 installed I can see the line in /etc/my.cnf, so this "seems" like a bug?
