I think what you are seeing is merely the code maturing. There have been many 
revisions and the functionality has been increasing. It may be that 
the 'root=' parameter is now specifically tied to a linux domu and causes a 
problem when used with nbsd, whereas in the past it was just completely 
ignored.

But you are right, in the past it was ignored. Whether what you are seeing is 
a bug or a feature, I'm not sure. All I know is that it is an option that has 
never been needed for a nbsd domu and for it to cause a problem now, seems 
completely within the realm of active development :)

I always wondered why xen couldn't just 'root = bootdev' when detecting a nbsd 
domu ...
