There was break between 1.4.1 and 1.4.2 (ISTR), such that "ipf" and
"ipnat" wouldn't be effective with the new kernel. Of course, new
binaries wouldn't have run with the old kernel, either, so that
wouldn't change the correct build order. Just a heads up.

Then also, kernel grovelers, notably "ps", won't work until they're
relinked with a new "libkvm" [but NetBSD 1.5 and later's "ps" falls
back on the proc file-system].
