Hrm. Almost the same as you. On mine that first comparison is actually
"!= //boot/kernel". Likely because I have "DESTDIR?=/" in /etc/make.conf.

Hrm. Suddenly all makes sense. I defined DESTDIR so that 'make world'
would continue to work normally (instead of doing buildworld/installworld)
and that probably happened around August '04.

So I guess if I get rid of DESTDIR and start doing buildworld/installworld
then I get kernel.old functionality again... however this tastes like a
bug to me. Perhaps that comparison should be:

"!= ${DESTIR}/boot/kernel" ??
