Refer to the comment section of /usr/src/Makefile for an
explaination of the correct procedure of the updating

 1.  `cd /usr/src'       (or to the directory containing your source tree).
 2.  `make buildworld'
 3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
 4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
      [steps 3. & 4. can be combined by using the "kernel" target]
 5.  `reboot'        (in single user mode: boot -s from the loader prompt).
 6.  `mergemaster -p'
 7.  `make installworld'
 8.  `make delete-old'
 9.  `mergemaster'                         (you may wish to use -U or -ai).
10.  `reboot'
11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)

You'll also see what the different make targets are representing
(e. g. make world = "buildworld + installworld, no kernel").
