With a quick look, it does not.
Look at: readahead_early and readahead in FC2
I believe that they are new,,, see below.
If you are bold you can add timers to each of the rc files and get
some statistics. Then add background (&) commands to selected ones.
Check for start etc so the right things happen.
Do this with care as many boot activities depend on a previous action
completing. It is important to find the slow ones that do not clutter
the dependency tree of the boot process.

The two differ in their input data file.
/etc/readahead.early.files
/etc/readahead.files
The list of files including libraries and fonts is long.
Perhaps long enough that local pruning and tuning may apply.
