Good, you can give karma to the upcoming unbound packages :)

You have to be careful with this, as some data is pushed into unbound on
demand. For instance, with openswan when you connect your VPN, the DNS
entries for the DOMAIN received by XAUTH is added to unbound using
unbound-control. It is also removed and flushed when the VPN tunnel goes
down. This kind of data should not be permanently added.

This is why I added /etc/unbound/local.d/ You should be able to populate
that directory using puppet or something similar.

I also added /etc/unbound/conf.d/ and /etc/unbound/keys.d/ where you can
put files in to be read by unbound on startup.
