not silly, cuz i do silly things sometimes. but i think my env is set
correctly:

test node which i desire to be a mail-client:
[sous-chef1-dev ~]# grep environment /etc/chef/client.rb
environment "dev"

again, mail-client should pick up the env override for relayhost
as "mungbeans.dev.dorqtown.com" instead of the default value from
the recipe attributes. but it's not.

test node which i desire to be a mail-server:
[sous-chef2-dev ~]# grep environment /etc/chef/client.rb
environment "dev"


in debug output, i do see it seeking out env info.

and fwiw, the chef clients are CentOS 5.6, running 0.10.4, RPMs
from RBEL (e.g. rubygem-chef-0.10.4-1.el5).

i'm running my own chef server, Ubuntu 11.04, 0.10.4-1.
