The handbook does say in section 23.4.2 that if /usr/src/UPDATING
contradicts something you read in the handbook, UPDATING takes
precedence so I guess it does cover itself. The steps in UPDATING seem
to work pretty well. I sometimes do mergemaster -iU at the second
mergemaster step in the "To rebuild everything and install it on the
current system" step as I mostly don't change the files that get
reviewed by mergemaster, otherwise I stick exactly to UPDATING and get
almost no problems.
