Bug#473889: Bug 473889 about grub-probe merged with 473209

[Mike Massonnet]

Hi,

I did a merge with 473209 which has the same error as I stumbled over,
and more information about the real problem (/boot/grub/devices.map).

Bastian, it breaks as-in it quits the configuration processing, and
forces me to run a reconfiguration to finish the apt-get install.

Btw, I did a quick touch /dev/sda.

Currently I have a machine in sid not updated with the latest packages,
when I will have time to upgrade, I will upgrade grub and the
linux-image separately.

Mike
