[chef-dev] Ohai resource with reload action doesn't refresh node['fqdn'] etc.

["Chris Fordham" < >]

Hello,

I do hope this is ok for this list as it seems to be core chef, although I  
don't discount the pebkac possibility.

This is the recipe which has a provider:  
https://github.com/flaccid/cookbooks_public/blob/master/cookbooks/rs_utils/recipes/setup_hostname.rb

Example output showing that reloading ohai hostname plugin doesn't  
actually reload:

As you can see the hostname successfully changed and  
ohai[reload_hostname_info_from_ohai] reloaded ran. But node['fqdn'] and  
node['hostname'] are not updated: Current Chef FQDN loaded from Ohai:  
localhost.localdomain (the old value). This is also the case if I added  
another recipe to the run_list after - node['fqdn'] is still the old one.

We've tried many different ways of loading and ordering, each with the  
same result: the ohai reload happens clearly before the log entries or  
subsequent recipes, but not changed.

Is this a bug, pebkac or otherwise? Help is much appreciated and I can  
lodge a bug if thats the case.

Best regards,
