Package: grub-common
Version: 2.02~beta2-22+deb8u1
Severity: normal
Tags: patch
The script /etc/grub.d/30_os-prober does not provide the correct device name
for booting the Hurd, e.g. when installed with crosshurd.
The bug also applies to the grub version currently in sid.
The patch changes provided device names from, e.g.:
(hostdisk//dev/sda,msdos2)
to:
hd0s2
This is the patch that solved the problem in my case, and may be correct:
