Current default version for FreeBSD is MySQL 5.7, also python 2.x is
deprecated and should be removed any time soon.
FreeBSD uses the `mysql_install_db` which generates a temporary root
password upon the first start. To the best of my understanding I haven't
seen any code in the formula that handles this method. So I added
a FreeBSD-scpecific block for initialization. While here, create
`/var/log/mysql` without which the server won't start if it doesn't
exist.
