Bug#666992: grub-pc: installation into partition broken, postinst script does not detect MBR installation

Package: grub-pc
Version: 1.99-20
Severity: important
Dear maintainers of grub2
I don't know if it was always like that, but the last update of grub2
failed in the postinst script, because it tried to install into
/dev/sda3
which was found via
grub-probe --target=device /boot
Yes, all my linux is in /dev/sda3, all of it. The error message is
# grub-install /dev/sda3
/usr/sbin/grub-setup: warn: Attempting to install GRUB to a partitionless disk or to a partition. This is a BAD idea..
/usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
/usr/sbin/grub-setup: error: will not proceed with blocklists.
#
I faintly remember that I *have* installed grub into sda3 before, but
that is no proof I assume.
Now, installation into the MBR works without a problem, and I am
anyway running it from the MBR.
So what I see here are two bugs:
* grub is not able to be installed into my /dev/sda3
* postinst is not able to detect that grub is already installed in MBR
Just to let you know
Norbert
