Check out the source tree ( 'cvs checkout src' with  
CVSROOT=anoncvs%anoncvs.netbsd.org@localhost:/cvsroot ), and in src first run  
'build.sh tools' ( you may want to specify where to put build tools,  
object files etc. - look at BUILDING for more detailed instructions )  
- - this will build the tools needed to build the kernel. You can  
probably build a -current kernel with the tools that come with 4.0  
but I wouldn't bet on it. Then edit your kernel config file ( sys/ 
arch/whatever/conf/GENERIC is a good starting point ) and run  
'build.sh kernel=WHATEVER'. That's it. make sure you have options  
COMPAT_40 in your jkernel config so your 4.0 userland will work  
( except threaded applications. That stuff changed radically from 4.0  
to -current )
The nice thing about this approach is that you can build kernels and  
userlands for any architecture supported by NetBSD independent from  
your host tools. For instance you could easily build a NetBSD/sparc  
kernel on a linux/x86 box.

have fun
