Wrong repository/mirror URLs due to unsupported fact 'os_maj_version'

[Flauschbaellchen]

After installing I get:

http://yum.puppetlabs.com/el//dependencies/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.
http://yum.puppetlabs.com/el//products/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Trying other mirror.

System: Centos 6.5
Puppet (Agent): puppet-2.7.25-2.el6.noarch

Bug: The fact os_maj_version was not yet supported
Fix: Fallback to the fact operatingsystemrelease or lsbdistrelease (both '6.5' on my system)

os_maj_version is supported in any facter that is still supported upstream.

Puppet 2 and Facter 1 are both EOL now.
