Hi, just a bikeshed now that you have an already working patch :), but
the generate_forwarding_headers() can be implemented as kernel make rules:
  http://les.ath.cx/DragonFly/fwd_hdr.diff.gz
I think it is better and cleaner than generating headers in config(8),
I have adjusted YONETANI's version a little bit, mainly in kmod.mk
1) use forwarder_${MACHINE_ARCH} instead of forwarder_i386
2) if MAKEOBJDIRPREFIX is not set, ${.OBJDIR}/forward_${MACHINE_ARCH}
is used, or forward_${MACHINE_ARCH} will be created in /usr/src/sys,
that's probably not what we want
3) nuke generate_forwarding_headers() in usr.sbin/config/main.c
Please review it:

Best Regards,
sephe
