custom kernel, make buildkernel and then?

Hope you can advise me. I have a FreeBSD 6.1 stable system for which I
want to build a custom kernel. However, I am scared to death (almost ;)
and just want to make sure I have it done the right way.
I have in the past used supfile with ports-all option and couldn't build a
custom kernel. Yesterday it dawned on me that I need sources for that, not
ports. So I ran cvsup with src-all option. Now, I followed these steps:
# cd /usr/src/sys/i386/conf
# mkdir /root/kernels
# cp GENERIC /root/kernels/LISTS
# ln -s /root/kernels/LISTS
then I used procedure 2 for building the kernel the new way.
# cd /usr/src
# make buildkernel KERNCONF=LISTS
It all went well without any complaint (I was really puzzled - when it
comes to IT, I usually see half-empty glasses...) but now I wonder. My
next step is supposed to be make installkernel KERNCONF=LISTS
Is it OK to do it on an already configured system? I have some usual
applications like php, mysql, apache, exim MTA configured and working. So
in other words I am trying to build a custom kernel not on a fresh install
but on an already working system (operating for 25 days). It is not a
webserver but it is running and needs these apps. My fear is that I am
likely to break something.
Have I done the right steps? Do you think I can progress with make
I have also a question about the last command in the recipe:
> Now, shutdown the system and reboot to use your new kernel.
Will shutdown -r now be enough? Or do I have to boot in single user mode?
Sorry if all of these seems obvious. I am new to FreeBSD. Thank you very
much in advance!
