How to get rid of STRICT SQL mode in MySQL

Question

This is a follow up to this question MYSQL incorrect DATETIME format

How to get rid of STRICT_TRANS_TABLES once and for all?

mysql --help report

Answer 1

So in the end I removed the MySQL Server I got from the mysql.com, reinstalled it via Homebrew and had to edit

/usr/local/Cellar/mysql/5.6.xx/my.cnf

Where I could comment out the darned STRICT_TRANS_TABLES.

However this doesn't explain why the default config overrides the one from /etc/my.cnf, but I spent too much time on this already as it is. And by the way I am still not sure what to do with the mysql.com provided distribution.
