trick for working with grub floppys

[adrian15]

I suppose you all already know this. But...

dd if=/dev/fd0 of=./super_disco_grub.img
mkdir /mnt/test
mount -t vfat -o loop ./super_disco_grub.img /mnt/test
cp /boot/grub/devices.map /boot/grub/alterna.map
Edit /boot/grub/alterna.map and replace /dev/fd0 and put /dev/loop0

Run:

/sbin/grub --map-file=/boot/grub/alterna.map

You can edit files in /mnt/test
and you can run grub from a "floppy" without speed problems.
