Bug#687162: grub-probe: fails with "error: no such disk."

[Daniel 'DaB.' Baur]

Package: grub-pc
Version: 1.99-22.1
Severity: important

Dear Maintainer,

if I run update-grub2 on my nearly fresh installed system, it fails (there
is no update at /boot at all AFAIS). The problem seems to be grub-probe,
maybe in a combination with grub-mount.

My /boot is a primary partition (/dev/sda1), / is on a LVM.

Sincerely,
DaB.
