Disabling automatic naming of machines in Amazon EC2

I run SharePoint 2010 in my Amazon EC2 instances. As a result, I do not want my machines automatically renamed by the EC2Config service when I stop / start them. This would totally screw up SharePoint as it does not behave well with machine name changes. Fortunately, Amazon EC2 has a way to do this via the EC2Config Service Settings executable or by directly editing C:\Program Files\Amazon\Ec2ConfigSetup\config.xml and changing the Ec2SetComputerName value to Disabled. The latter is quite handy as I had to stop and restart instances recently due to some deadlock issues.
