Knoppix (or another run-from-cd linux) may do exactly what you want. Take
a look at this: http://www.knoppix.net/

If you want to roll your own distribution, I think it would be possible.
I did some experimenting with building a "loopback linux," and I think
those techniques could work to build an "in place" linux- using a free
hard disk partition. The general procedure would be as follows:

        0. Load the kernel and initial ramdisk (isolinux).
        1. From linuxrc do prep work:
                a. Format partition where your new root is going to be built.
                b. Add tmp and proc directories to the new root.
                c. Fill partition with a pre-configured installation (similar to a
                backup restore operation).
                d. Use pivot_root to start using the built-in-place linux.
        2. Normal startup scripts execute (i.e. /sbin/init)

I documented what I did here:
