Minor issue specifying external bosh director

[a2geek]

This is simple to overcome, but the external BOSH director needs more than the suggested configuration. When I only added the configuration:

  external_bosh:
    address:  (( vault "secret/exodus/" params.env "/bosh:url"))
    cacert:   (( vault "secret/exodus/" params.env "/bosh:ca_cert"))
    username: (( vault "secret/exodus/" params.env "/bosh:admin_username"))
    password: (( vault "secret/exodus/" params.env "/bosh:admin_password"))

I get the following error:

STDOUT:
2 error(s) detected:
 - $.meta.external_bosh_password: secret /secret/exodus/gdc-prod/bosh:blacksmith_password not found
 - $.meta.external_bosh_username: secret /secret/exodus/gdc-prod/bosh:blacksmith_user not found

Looking at external-bosh.yml, I noted the meta references which look for a different name. On a hunch, I tried this:

meta:
  external_bosh_password: NOT PRESENT
  external_bosh_username: NOT PRESENT

and that works. The text never makes it into the manifest, so it is functional...

Is there some more natural method to bypass this hack?

Thanks!
