Re: config <kernelname>

Steven,

Your last email woke me up.  I was stuck on stupid.  While I had 
downloaded the sources for 5.0 it was not registering that I am not 
doing a native build and I am doing a cross compile since I am presently 
executing NetBSD 3.1.  This has now drawn my attention back to NetBSD 
Guild chapter 30 which I had formerly dismissed as irrelevant to my 
instance.

I think I'm going to go try again now that I have the picture of my 
situation correct.  Once I get this going, I'll try building a custom 
kernel for my old Sun 3/50 diskless unit.  With only 4MB on that, the 
generic kernel is too big for its meager resources.

Thanks to Steven and Paul for responding,

David
