I think you're on your own, since there is not much documentation to describe
the inner workings of NetBSD. Yes you can read the source code, but it's not
the substitute for proper documentation. I recently bought "Solaris Internals"
book that describes in detail OpenSolaris kernel architecture, why isn't there
something similar for NetBSD?? There are some howtos at
http://www.netbsd.org/Documentation/ which are brief and don't go into much
detail.
