How to handle large number of disk devices in "arbitrary" order?

For fstab just use fstabkey:uuid in your disk_config line (which will be the
default 4.0). For grub you will have to use some local hacks AFAIK. I'm using
for grub 1 in boot/grub/menu.lst/preinst

preinst_file=$2
if grep -q "##UUID##" $preinst_file ; then
  part="$FAI_ROOT`grep "##UUID##" $preinst_file | perl -p -e 's/^.*##UUID##([^#]*)##.*$/$1/'`"
  part="`echo $part | sed 's#//#/#g' | perl -p -e  's#(.)/$#$1#'`"
  uuid="`blkid -s UUID -o value \`mount | grep "on $part type" | awk '{ print $1 }'\``"
  perl -p -i -e "s/##UUID##[^#]*##/UUID=$uuid/" $preinst_file
fi    

with boot/grub/menu.lst/DEFAULT containing

title Debian GNU/Linux
root (hd0,0)
kernel /vmlinuz root=##UUID##/##
initrd /initrd.img

Hope this helps,
Michael
