If you follow the handbook,
you are not supposed to reboot at all after installkernel.
I think it was advised once, but it does no longer say so,
it just says "drop to single user".

Well, it still says "[single user] also minimizes any problems from  
running the old world on a new kernel." which you don't actually do if you  
follow the instructions.
