Hello,

I am testing the cloud-init behavior of a pristine CentOS 7 cloud image 
downloaded from 
http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2 
in CloudSigma.

Right now the only reason it is not working of the box, it that there is a 
missing dependency
of the cloud-init package. The CloudSigma data source requires pyserial to 
be present,
but it is not installed by default on this image.

Is it possible to add the pyserial package as an extra dependency? It is 
already listed as 
a dependency in the requirements.txt of cloud-init sources and in 
/usr/lib/python2.7/site-packages/cloud_init-0.7.5-py2.7.egg-
info/requires.txt so
adding pyserial as RPM dependency will be consistent with cloud-init Python 
sources.

The same reason and observations are applicable for the CentOS 6 cloud-init 
package.

Thanks!
