And from experience this is what it will do: replace
/boot/kernel/kernel which is my custom kernel with a GENERIC kernel.
As it seems that freebsd-update works by comparing a hash of
/boot/kernel/kernel with the GENERIC kernel's hash I checked the md5
and sha1 hash of /boot/kernel/kernel and /boot/GENERIC/kernel. They
differ (see [3]).
So why is freebsd-update going to overwrite my custom kernel? And how
can I prevent it from doing so?
Read man (5) freebsd-update.conf. Particularly the COMPONENTS portion
that explains how to update world without changing kernel.
Thanks for pointing this out. I might change my freebsd-update.conf to
not update the kernel. But still I believe this to be more of a kludge
than a solution: in my opinion the handbook suggests that a custom
kernel should be detected and left alone. But at the same time a GENERIC
kernel in /boot/GENERIC should be patched.

That needs to be updated.
However, freebsd-update will detect and update the GENERIC kernel in
/boot/GENERIC (if it exists), even if it is not the current (running)
kernel of the system.

Furthermore if I remove the kernel option from the COMPONENTS in
freebsd-update.conf I think I will not get the kernel source patches
anymore, right? Which in turn means I have to get them via some other
mechanism, no?
See UpdateIfUnmodified in the man page. You can specify a regex pattern
that prevents the kernel from being modified but still downloads the
sources.
I wasn't thinking when I wrote this. Freebsd-update pulls *binary* copies
of files, so you're not ever going to get the src files to rebuild your
kernel from freebsd-update. You need to pull those in using svn.
