automysqlbackup ERRORS REPORTED: MySQL Backup error Log Warning: Skipping the data of table mysql.event. Specify the –events option explicitly.

I was receiving email error messages from cron like this from my autbackupmysql on a regular basis:
ERRORS REPORTED: MySQL Backup error Log for somehost.com.dxa - 2014-05-01_06h26m
-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.

It turns out that mysqldump now warns you if the events table is not being dumped. So to get rid of the warning either ensure the table gets dumped when you do a backup or tell mysql explicitly not to dump it. I chose the former approach as it is a backup after all.
Simply add the following line to /etc/mysql/my.cnf

[mysqldump]
...
...
...
events

This tells the mysqldump program to explicity include the events table, and removes the warning. You can see a discussion about this option here.
If you are using debian, you will need to add that section to the /etc/mysql/debian.cnf file also as automysqlbackup uses that file for its configuration instead. See debian bug report for more details.
