Yikes. When I originally posted I cleaned up identifiable and I took away
too much. I actually was passing everything through like I should. Since I
deleted my test data from the original post, Here's the hiera data I am
having trouble with:
ucb::mail::senders:
"@%{::clientcert}":
relay: 'berkeley.edu'
And the resulting hiera call that returns the unexpected entry:
# hiera -h ucb::mail::senders ::clientcert=myhost.ist.berkeley.edu
::environment=arusso_postfix ::fqdn=myhost.ist.berkeley.edu -c
/etc/hiera-test.yaml
{"@%{::clientcert}"=>{"relay"=>"berkeley.edu"},
"@myhost.ist.berkeley.edu"=>{"relay"=>"berkeley.edu"}}
The template generated on the host also reflects the fact that the extra
entry is being sent over. I also tried it with other facts, like fqdn and
hostname, and confirmed they all exhibit the same behavior.
Thanks,
Aaron
