Why do you want to do that? If you want a ramdisk based root
filesystem then use that. If you wand a root filesystem on harddisk,
that use that. I see no need (and no sense) in booting with an
initial ramdisk and then switching to a harddisk.

You have to design your system. You must understand which services
are needed where, and use those, but not anything else. It definitely
makes no sense to start network servers and application stuff that
keeps running in the background if you later intend to pivot_root to
a different filesystem.
