I only have this experience from RedHat, CentOS versions as these are the only systems I'm maintaining mysql servers on.

As far as I understood it affects all servers, but I wanted to be on the safe side. But I can take these out.

Btw: The acceptance tests even test on that output: https://github.com/puppetlabs/puppetlabs-mysql/blob/master/spec/acceptance/mysql_backup_spec.rb#L34
