I was thinking of some more general way of accomplishing
what machdep.booted_kernel does, i.e. mostly where to
point kvm_mkdb at.
I agree that version is probably safe to use, so perhaps
simply checking all of /netbsd* for a version string matching
the running kernel's would be better than trying to improve
