That is what I thought it would do, based on the docs. However, 
when I recently ran freebsd-update on a FreeBSD 9.0 machine with a 
module-less custom kernel at /boot/kernel/kernel, it fetched a 
GENERIC kernel and overwrote the custom kernel with it. 
Interestingly, it didn't bring in any modules; it just overwrote the one file.
