Thanks Cary, before I changed to compile phase, the code was like this and  
showed the same problem.
I left it in compile phase as it seemed to be a good way to set the  
hostname as early as possible.
Either way, the reload is evident early before any refs to node['fqdn'] in  
the same recipe or subsequent recipes in the run_list.
Unfortunately have had no luck. Might be time to try submitting a chef bug  
now :(
