File os-prober-1.49-fix-grub2.cfg-parsing.patch of Package os-prober
From: Andrey Borzenkov <arvidjaar@gmail.com> Subject: fix parsing GRUB2 grub.cfg References: bnc#796919 Fix several problems in parsing of grub.cfg by linux-boot-probes/mounted/40grub2 1. Look for /boot/grub2-efi/grub.cfg as well (openSUSE 12.2) 2. It checked for literal "(on /dev/.*)" to filter out menu entries added by another os-prober on target system. But grub.cfg now includes TRANSLATED strings, so this check will fail if grub.cfg was created in non-English locale. Use menu entry ID to check whether entry was added by os-prober (it always starts with osprober-). Suggested by Vladimir Serbienko.
