Sorry for this long silence. Unfortunately I have only some hours/month 
spare time to work on this.
There are kind of "to be expected" incompatible options, of course, but 
this one hit me some years before. Especcially for newbies, it's not 
clear why these options shouldn't work together.

I think rc.d/var should be able to populate a named compliant /var. 
Therefore it needs at least named.conf and named.root.
My idea was to save them in /usr/share, where many other (sendmail e.g.) 
template duplicates also reside. When chrooting to /usr/share/namedb, it 
also fails if I don't have the original installed /var, like if /var is 
a freshly populated memory file system.

Is there anything wrong with my patch?

Thanks,
