the way lilo works it doesn't actually put the bootloader on the md device at 
all, but instead puts it on each of the physical disks' boot sections.  so 
the configuration could be thought of as "and put one here too".

this makes a very large assumption that you know your disk has failed.  think 
about what happens if the first time it fails is when you turn on your 
computer :)
