boot from raid1 mdadm version 1.2 partition

[Marc Auslander <marcausl@gmail.com>]

Earlier posts seem to say this should/might work.

I made an mdadm v 1.2 partions, and put a copy of my root file system
on it.

update-grub doesn't see it at all.

if I try to boot by hand, I can get grub to boot the kernel but then I
get mysterious error messages about not being able to mount /dev/pts
and fall into the recovery shell.  It appears that my raid partions
have not been assembled.

Any hints.

Does anyone actually have boot from raid1 version 1.2 working?  If so,
could you post the grub.cfg entry that makes it work?
