How to write a pre-mount startup script?

How to write a pre-mount startup script?

I want to create a bootup script that runs before the root filesystem /
has been mounted as I want to use dm-cache to cache it. The script is
supposed to contain cache setup commands.
Where would I need to put such a script and what format does it need to have?
I cannot find any useful documentation by googling.
Running Fedora 17, Kernel 3.9.10.
