Ah, right.  So what would be the simplest way to enable this use case? 
Perhaps a generalization of AWS::CloudFormation::Init that allows the 
package names to be objects (that evaluate to strings, of course)?  Maybe 
allow, e.g., "yum" to be associated with not a map but rather a list of 
pairs (2-element lists)?

Thanks,
