Bug#674560: A patch to add support for reading Fedora's grub2 config file

[Hedayat Vatankhah <hedayatv@gmail.com>]

Package: os-prober
Version: 1.53
Tags: patch


Currently, Fedora installs grub2 inside /boot/grub2 rather than 
/boot/grub. Therefore, grub.cfg resides in /boot/grub2/, while os-prober 
assumes that grub.cfg is in /boot/grub/. Therefore, proper boot 
arguments for Fedora installation is not retrieved. This patch provide a 
fix for this problem.
