It's possible to assert that a fact value is non-empty in puppet code using the "assert_type" function:

$ bundle exec puppet apply -e "notice(assert_type(String[1], \$facts['fluffy.bunny']))"

Error: Evaluation Error: Error while evaluating a Function Call, assert_type(): expects a String value, got Undef (line: 1, column: 8) on node localhost

Facter (v4) also differentiates between the fact has an empty value vs is absent:

$ bx facter missing -j

  "missing": null

$ bx facter empty -j --custom-dir /home/josh/work/facter/custom_facts

  "empty": ""

$ cat custom_facts/empty.rb

Facter.add(:empty) do

  setcode { "" }

end

Given that I don't think we want to change facter's exit code.
