.get_enterprise_linux_version ⇒ Object

Return the enterprise linux version of the running machine…or an exception if it’s a non-enterprise version of linux. At this point we will only test for CentOS … but in the future we can test RHEL, and any other compatible ones Note the version is a single (major) number.
