Proposal for including heat-cfntools in Fedora cloud images

[Steven Dake]

Hi,

I would like to propose an idea of including the heat-cfntools package 
in the base cloud images provided by Fedora.  In the past, I have been 
opposed to this idea because our cfntools would conflict with AWS 
cfntools.  I have found a solution to this problem.

heat-cfntools places its files in /usr/bin.  Amazon places their files 
(with the same name) in /opt/aws/bin.  The heat-cfntools package 
provides a script called cfn-create-aws-symlinks which creates symlinks 
in /opt/aws/bin to the cfntools in /usr/bin.

If we install heat-cfntools in the base image, heat itself can run 
cfn-create-aws-symlinks as part of the bootstrapping process inside the 
vm, avoiding any collisions.  In effect, the symlinking would only 
happen inside a Heat launched vm as part of the bootstrapping scripts we 
provide.

For more details of the bootstrapping process used in Heat, please read:

Other distros such as debian, ubuntu, SUSE, etc can follow this same 
model of including heat-cfntools in their distributed qcow2 images.

This would get the heat developers out of the business of providing 
prebuilt images like we do here:
