Bug#614023: grub-common: /etc/grub.d/30_os-prober sets invalid boot device for the Hurd

[Adrian Glaubitz]

Package: grub-common
Version: 1.98+20100804-14
Severity: normal

Hi,

as the subject already suggests, the os-prober script sets an invalid boot
device for a parallel installation of Debian GNU/Hurd. This will make
the Hurd fail to boot when booting it from a chainloaded GRUB2 (after
upgrading a previously installed GRUB1).

The affected line is:

    "multiboot /boot/gnumach.gz root=device:hd0smsdos2"

where "hd0smsdos2" is not a valid identifier for a partition in the Hurd.
The proper naming is "hd0s2" and after correcting the device name, that is:

    "multiboot /boot/gnumach.gz root=device:hd0s2"

the Hurd boots properly again. I think, that at some point one of the migration
scripts from GRUB1 to GRUB2 or the os-prober script introduce an additional
"msdos" label into the device name which eventually makes the device name
invalid.

Regards,

Adrian
