[chef] Re: Re: Re: Not able to use IAM role with knife ec2 command

I think that the docs are ambiguous, but when they say "use", they mean "set". That's why it only applies to instance creation. Saying "the profile to apply" is clearer about it being a set operation.

My workstation is an ec2 instance having an IAM role. I don't want to keep EC2 credentials on this instance. Knife ec2  should be able to use the IAM role attached with the instance. According to the documentation --use-iam-profile parameter does exactly that. But it i not working when I try to use the same.

The help options are going to be specific for the subcommand you're
executing. "--iam-profile" makes no sense in the context of listing
servers.
