I used to do that each update withthe help of a bit of command line code,
until I timed readahead.  My timing tests of booting to the desktop with FF
open showed no difference in the /total/ time, whether or not readahead was
enabled.  At that point I added FF to my session so it opens automatically
now.

None of my tests showed any benefit to readahead.  Readahead just moves
time around.  I was quite surprised.
