Sorry, I wrote this incorrectly. In my case, /dev/sdb1 = /dev/md1 and 
/dev/sdb6 = /dev/md2.  Remember, my md devices each have a drive missing 
at this point. I had the mdX devices started and mounted, and I rsynced 
from /dev/sda1 to /dev/md1, /dev/sda6 to /dev/md2.

Why do I have to do this? I haven't seen this in any "recipies". My 
Linux setup only has three partitions:   "/", swap, and "/home".

My experience with fixing bootloaders in the past is that I can boot up 
with a LIVE CD or rescue disk, chroot say into /dev/sda and run lilo 
right to fix the bootloader on /dev/sda. I do this when need to move my 
OS drive from an IDE to SATA or back again.

I'm not sure I understand what you're saying about mounting /dev, /proc 
and /sys.
