I was under the impression that building across releases was not
recommended and/or fragile. From /usr/src/UPDATING:
NOTE: FreeBSD has switched from gcc to clang. If you have trouble
bootstrapping from older versions of FreeBSD, try WITHOUT_CLANG
and WITH_GCC to bootstrap to the tip of head, and then rebuild
without this option. The bootstrap process from older version
of current across the gcc/clang cutover is a bit fragile.

Does it do that? According to the documentation, it only installs
the new kernel. Other components (which I read as also the src
component) are installed only by the second invocation, after you
have booted the new kernel. Is this another case of the documentation
being outdated?

What extra make install?
To recapitulate:
This is how it works with GENERIC kernel:
freebsd-update -r XX.Y-RELEASE upgrade
freebsd-update install
reboot
freebsd-update install
This is how Julian said it works for him with the custom kernel,
except I replaced fetch with upgrade:
1) freebsd-update -r XX.Y-RELEASE upgrade
2) freebsd-update install
3) make kernel KERNCONF=3DMYKERNEL
4) reboot
5) freebsd-update install
In my understanding in step #3 you don't have the new sources yet,
so how do you compile the new kernel? Or do you have them?
Thanks,
