The right answer is to read and follow the instructions in
/usr/src/UPDATING. (They are near the bottom of the file.)

The list above missed adjkerntz (not needed if the hardware clock is
running UTC). Adding swapon -a is a good safety net, too. I was
recently bitten when I forgot.

But rather then generate more poor or incomplete examples for people to
trip over, the canonical answer should be to follow the instructions in
UPDATING.
