Bug#548320: grub image too large for floppy

[ael]

grub-install --root-directory=/floppy /dev/fd0
was too big for a 1.4M floppy with ext2

Using a vfat filesystem gave warnings about installing on a
partitionles disk, and messages about blocklists.

I saw something about this problem in a grub bug report somewhere.
So at first sight grub-rescue-pc is broken?

Using --force did however work: I can't see why blocklists should
not be safe on a ro boot rescue floppy?

There needs to be a note, perhaps along the above lines, on how to 
produce a floppy image.
