<p>Defines the default patch baseline for the relevant operating system.</p> <p>To reset the AWS predefined patch baseline as the default, specify the full patch baseline ARN as the baseline ID value. For example, for CentOS, specify <code>arn:aws:ssm:us-east-2:733109147000:patchbaseline/pb-0574b43a65ea646ed</code> instead of <code>pb-0574b43a65ea646ed</code>.</p>
