typed too fast and now proofed... corrections

mkdir /boot2
mount /dev/sdb1 /boot2
rsync -rvup --delete-after /boot/* /boot2
umount /boot2
 
mount /dev/sdc1 /boot2
rsync -rvup --delete-after /boot/* /boot2
umount /boot2

mount /dev/sdd1 /boot2
rsync -rvup --delete-after /boot/* /boot2
umount /boot2

do this once in a while - probably after new kernels are installed and
you are set for a disaster
