I just checked, the new kernel sources are not installed by the
first update. I tried this on a 10.4 system with a custom kernel:
# uname -a
FreeBSD ip-172-31-46-244 10.4-RELEASE-p13 FreeBSD 10.4-RELEASE-p13 #0:
Wed Nov 7 09:12:40 UTC 2018
aram@ip-172-31-46-244:/usr/obj/usr/src/sys/FCTARGET
amd64
#
# freebsd-update -r 11.2-RELEASE upgrade
# freebsd-update install
Installing updates...
Kernel updates have been installed. Please reboot and run
"/usr/sbin/freebsd-update install" again to finish installing updates.
At this point the new kernel sources are *NOT* installed. There is
no point in recompiling the kernel here, as you will recompile the
old (10.4) kernel.
If you reboot now, you will get the new (11.2) GENERIC kernel, not
the custom kernel. After reboot:
# uname -a
FreeBSD ip-172-31-46-244 11.2-RELEASE-p4 FreeBSD 11.2-RELEASE-p4 #0:
Thu Sep 27 08:16:24 UTC 2018
root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC
amd64
We can now run freebsd-update install again, to finish the upgrade.
After that is finished, we can now recompile and reinstall the
custom kernel.
$ cd /usr/src
$ make buildkernel -j32 KERNCONF=3DFCTARGET
$ sudo make installkernel KERNCONF=3DFCTARGET
$ sudo reboot
After reboot we'll have our custom 11.2 kernel.
As you can see, we had to boot into GENERIC to do the update. The
kernel sources were not updated by freebsd-update(8) in the first
invocation, only by the second one, after the GENERIC kernel was
installed and booted.
