Err, I would hope you could get a system to reboot without extra parts. :)

First, get it booting up to your shell script or whatever (I don't know if
the kernel init= parameter will accept an interpreted script, if not, then
maybe consider an initrd with a /linuxrc file. You could also butcher the
existing inittab, or create a new /etc/rcS.d file, but that's a little
harder to undo if needed.)

Then, have the script mount the target filesystem read/write, read some
state information you left on the filesystem to tell it what step to jump
to (STEP=$(cat /path/to/file), do that test (case $STEP in 1) foo;; 2) bar;;
esac), recording the results to disk, then rewrite the state information
(echo $(($STEP + 1)) > /path/to/file), remount read-only, and reboot.
