You can do root raid NOW...

I understand why you think in these terms, but there's a much easier
way of doing things that works *NOW*, using the current Debian
Install onto a small (20-64MB) partition. Install Debian on it.
Reboot, set up your RAID devices. Reboot again into single user mode.
Copy the contents of the small partition to the raid device. Change
your configuration so that the small partition will now be /boot.
Modify your /etc/lilo.conf appropriately. Run lilo. Reboot
Sure, you just wasted 15-60MB, but who cares. That's what, $.15 these
I've *done* this, more or less (I had to compile the new raidtools and
patch kernels, etc, this was a year ago), and it works fine. If you
have the option to use a smart boot manager (say, MILO on the alpha,
or maybe GRUB on the i386?), you can keep a cold copy of /boot on the
spare bit of the beginning of your second root disk and get to it
