Bug #73544 /usr/my.cnf is not included as a default option. Eg. mysqld --help --verbose

Description:
When you run, "mysqld --help --verbose", /usr/my.cnf is not included as a default option file being read.

Also, if included, what is the hierarchy of /usr/my.cnf among other default locations? 

How to repeat:
[root@localhost ~]# mysqld --help --verbose|less

Usage: mysqld [OPTIONS]

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf

Thank you for the bug report. /usr/my.cnf doesn't makes part of the default
options please see:

However you can change the bug report to a Feature Request.

Thanks.
