The 'domain' and 'search' options are mutually exclusive according to 
the manpage, I'd remove the 'domain' option.

> root at linuxvmware:~# nslookup linux1
> Server:         10.5.1.30 <http://10.5.1.30>

I don't know whether nslookup always searches domains - what happens if 
you 'nslookup linux1.my.lan' or 'ping linux1' instead?

Maybe you should also remove that line, as your upstream servers won't 
be aware of your local zones.

Cheers,
Adam.
