You do not need either.
The readahead process preloads the buffer cache with files that might
be paged in one 'page demand triggered' read at a time. This can
speed things up of boxes with enough DRAM.
BIG Programs like OO that are started with a wraper script could
use this trick to advantage in some cases.

/etc/init.d/readahead: /usr/sbin/readahead `cat /etc/readahead.files` &
/etc/init.d/readahead_early: /usr/sbin/readahead `cat /etc/readahead.early.files` &
So the difference is /etc/readahead.files and /etc/readahead.early.files.
