Bug#502446: debian-installer: grub-installer is not updated for grub-pc introduction

[Osamu Aoki <osamu@debian.org>]

Hi,

As I looked more in detail, debian-installer works fine (does not over
write unrelated data) and usable if MBR is used as BIOS emultion mode
boot loader. (I.e., installed to /dev/sda (hd0)

So problem is when installing to /dev/sda3 or in other word to (hd0,3).

Since this causes data loss, this could be considered grave.  But
changing d-i this late may not be good idea.  If so reminder not to
install to places such as /dev/sda3.

Anyway, installation needs to do few manual tricks including gptsync.

Documenting this as short comments in release note is good idea.
