How many Linux distributions support Openstack

Ubuntu is one of the first distributions that started to show a support for Openstack. They have been very active from the beginning and continue to expand in the cloud. As an example this video can summarize how Ubuntu and Canonical has been involved in the project:

But is Canonical with Ubuntu the only Linux distribution that is interested in supporting and popularizing a wide adoption of Openstack [2] and open cloud standards? Likely they are not alone. There are already two other main distribution like Red Hat  SUSE that joined the Openstack Platinum Membership club as well ;) [1].

With all these efforts and livid community this is only a matter of time to see this to be come a next Linux of the Internet Cloud in the Open software world ;)
