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
Also here is the provider: https://github.com/flaccid/cookbooks_public/blob/master/cookbooks/rs_utils/providers/hostname.rb
Maybe there is a way to debug if nobody has any ideas? Failing that I think I will need to raise a bug - I'm just not seeing how the code is wrong if the reload is occurring visibly early enough.


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,
