Martin: Installing grub2 to a PBR (with "grub-install --force
/dev/sdXY) and therefore using block lists is theoretically less
robust than installing grub2 to an MBR but there are enough people
using block lists with grub and lilo that this claim seems to be
almost-FUD...
Cameleon: You can choose to install grub2 to a PBR by refusing to
install it to the MBR. d-i'll prompt you to provide a device - and it
accepts a partition.
