Both methods install the new > kernel on a running machine. "make buildkernel" uses the compiler toolchain that was compiled by a previous "make buildworld". "config / make depend / make" uses the the toolchain that is currently installed on the running system. If you're updating across certain types of changes to the toolchain, you need to use the buildkernel target. You'll probably ask, "Why can't I do buildworld / installworld / config?" In a lot of instances you can, *except* when the userland depends on features of the new kernel. People get bit there too. As has been pointed out ad nauseum on this list, in many cases you can get away various short-cuts. But if you run into problems, the first thing that a lot of people (including myself) will say is "go follow the instructions in src/UPDATING". These instructions were written by people who understand all the bizarre edge cases that can happen during upgrading.
