I switched to Foreman 1.2 (currently 1.2.0+debian0.3) after upgrading the Puppet master to Debian Wheezy. This required a new Foreman database due to no longer sharing with Puppet. At some point during the nightlys new Fedora hosts would not get their Properties set. Facts appear to be imported OK looking through the web interface.

We use Fedora 18 (Puppet 2.7.18) on desktops and a mixture of Debian 6 (puppet 2.6.9) and 7 (puppet 2.7.18) on the server side. Debian hosts do not have this problem.

Single Puppet master and Foreman. Facts imported via /etc/puppet/node.rb.

production.log contains:
