This is why the recommended update process is (in part):
# make buildworld
# make buildkernel
# make installkernel
Followed by a reboot into single-user mode before doing the installworld.
If the new kernel doesn't boot, you've still got the previous one in
/kernel.old, so you can just boot from that one and carry on without having
trashed any part of your system.
If installworld somehow manages to make your system unbootable, you have a
- boot single-user and try to fix things with the tools in /stand (or
/rescue on 5.x)
- boot CD #2 and try to fix things with the tools in the live filesystem
- restore from backups (you do have backups, right?)
Personally, I've made plenty of unbootable kernels, and a few worlds that
behaved strangely in places, but never an unusable system (fingers crossed
