Thanks guys, I did not realize "defined" was for resources only, not variables.
The custom fact is created using a custom fact creator "fact", which makes other custom facts out of strings in a text file. the text file itself is managed by puppet. http://www.devco.net/archives/2008/06/16/rework_of_puppet_facts_for_etcfactstxt.php And so it is normal that the text file based custom facts do not exist in the first run... Thanks, Mohamed.
