I'd like to add that the order in which kernel and world are
to be installed, combined with the suggestion to install world
in single-user mode, is provided to minimize the risk of
accidentally rendering the systen unbootable or damaged.
That's why the instructions in /usr/src/Makefile should be
taken as _the_ recommended method when updating from source.
Check the comment header of /usr/src/Makefile for details.
