[Bug 1109339] [NEW] os-prober fails to output in chroot environment thus failing update-grub

[undisclosed lastname]

Public bug reported:

while in chroot, os-prober returns nothing, therefore update-grub fails
to create entries for auxiliary OS. This happens on both copies (except
fstab) of the same system on different disks, while it is working fine
without a chroot (in both cases).

tested with and without mounting disk into chroot

Description:	Ubuntu 12.04.1 LTS
Release:	12.04

  Installiert: 1.51ubuntu3

I WAS on IRC and os-prober is not supported from grub team.
