A nice trick for easily recovering from unbootable kernels is
nextboot(8). Try man nextboot
I don't have much experience with this other than once I ran a server from home
and remotely ssh'ed to it to do maintenance. One of the things I learned from
that experience was that you can easily patch your services any time there is a
new threat, all you have to do is patch your code, recompile, and restart
service. If you are not sure it will ever come back up when you restart, you
can leave it patched and restart it when you are more comfortable. When it
comes to the kernel, don't upgrade it unless it's ABSOLUTELY necessary because
you have to reboot each time; unless of course, some genius out there has
figured out a way to do it without a reboot.
Just my two cents,
