Bug#850601: desktop-base does not install on live images

[Alf Gaida <agaida@siduction.org>]

Package: desktop-base
Version: 9.0.0
Severity: important
Tags: patch

Hi,

desktop-base don't install on live images, reason is that grub don't find a canonical path. 
I would call it a regression as desktop-base 8.0.2 works without problems.

The attached patch probably isn't a solution, more of a workaround.

Cheers Alf
