I was indeed the run_mode. Thanks for the tip.
When run_mode is the default of user
irb(main):001:0> require 'puppet'
=> true
irb(main):005:0> Puppet[:run_mode]
=> "user"
irb(main):003:0> Puppet::Node::Facts.terminus_class = :yaml
=> :yaml
irb(main):004:0>
Puppet::Node.find('ubuntu1004desktop.localdomain').parameters["operatingsystem"]
=> nil
However if run_mode is master (I changed to code to get this result)
it gets the right facts (the ones from the yamldir)
irb(main):001:0> require 'puppet'
=> true
irb(main):005:0> Puppet[:run_mode]
=> "master"
irb(main):003:0> Puppet::Node::Facts.terminus_class = :yaml
=> :yaml
irb(main):004:0>
Puppet::Node.find('ubuntu1004desktop.localdomain').parameters["operatingsystem"]
=> "Ubuntu"
Unfortunately there isn't a great, non-hacky way to change the
run_mode in a script that I see. I'll see if I can find the place in
the code where finding the node's facts depends on run_mode and get
rid of that.
