samba - May 2012 - Secondary DNS - samba 4 domain

How do I do about setting up a second samba DC as a DNS server?  I have 2
DCs in the domain (setup via the How-to on the wiki)

If I try to follow the steps I used for the first controller on the second,
bind won't start because /usr/local/samba/private/dns hasn't been
created
or populated. (I'm using the dlz backend).  Searching the wiki has provided
nothing.  How to I create the needed ldb zone files?  Do i just copy them
from the first machine?

I think you would just need to configure bind on the second machine as a 
backup dns.

It's slightly more involved. First you have to make sure that DNS
partitions are getting replicated between two DCs. If the DNS
partitions are not replicated correctly you won't be able to run DNS
server on secondary DC. Next step is to use samba_upgradedns script to
"fix" the provision on secondary DC and to create the files required
by DLZ backend.

The main issue reported by few users is that the replication fails at
times and I have not yet been able to figure out the root cause of
this. So if you notice issues with replication, let me know.
