Hi Evan,

In your email from July 5, you mentioned that primaries will work in the 
9.17 branch. I use FreeBSD which is on the 9.16.x train.
Can you please commit the code change to the 9.16.x branch to make the 
'primaries' work in the ESV branch?

I'm a long time bind user, and support your organization making these 
small, but important changes.

Thanks,
Rudy
