Hi Robert,

It doesn't break compatibility with MS, unless you're talking about the 
RSAT DNS tool, which is a lot more cumbersome than a text editor anyway 
and it's pretty much assumed that if you're using Samba you're a Linux 
sysadmin, so not being able to use the RSAT DNS tool should not be a 

I haven't read Mark Andrew's comment, not being on the Bind list, but I 
can't see how a problem with flat file is not also a problem with DLZ. 
After all, that's only the storage method, not the system.
