+Subject: Improve btrfs handling on os-probing for grub2
+Patch-mainline: never
+
+References: bsc#892364
+Signed-off-by: Egbert Eich <eich@suse.com>
+
+Currently probing of a grub2 config file is broken if
+the root/boot fs is btrfs. This is due to a patch picked
+from Fedora which attempts to determine the location of
+the kernel and probe for it.
+This code has meanwhile changed on Fedora, however the
+new version works no better than the old one.
+It is possible that this code works under very special
+circumstances of the Fedora system, however it is by no
+means valid.
+Our goal is to
+a. determine the location of the kernel in the mounted fs
+ regardless whether the grub2 config specifies an absolute
+ or relative path to the kernel file.
+b. Prepend the correct prefix if grub2_btrfs expects an
+ absolute path (either because the current grub2 fs isn't
+ btrfs or absolute path addressing is explicitely requested).
+c. Attempt to handle the location of the kernel file correctly
+ if this lives on a separate btrfs subvolume.
+ (Currently this only works if the path to this subvolume is
+ identical to the fs path).
+
+Signed-off-by: Egbert Eich <eich@suse.de>
+
+v2:
+a. Fix missing linux16/initrd16 parsing in entry result
+b. Fix kernelfile path if separate boot partition on btrfs

+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.

++BTRFS is a new filesystem which combines the filesystem with logical volume
++management (subvolumes). For further information, see:
++ https://btrfs.wiki.kernel.org/index.php/Main_Page
++ https://btrfs.wiki.kernel.org/index.php/FAQ
++
++In order to support BTRFS, a number of changes were necessary to os-prober,
++os-probes/common/50mounted-tests, os-probes/mounted/common/90linux-distro,
++linux-boot-prober, and linux-boot-probes/common/50mounted-tests.
++
++The biggest impact will be to grub2 where there is additional information
++output by os-prober and where, if a BTRFS subvolume is being used for root,
++the parameters for linux-boot-prober have changed.

+Recognize initrdefi and linuxefi too. Whether linux/initrd or

+Subject: [PATCH] Use /tmp over /var/lib for transient files
+
+Create transient mount point in directory /tmp rather than /var/lib
+which is not available during transactional update. Also clean up the
+count_last_label function for not relying on /var/lib/os-prober/labels
+file for the caculation.
+
+https://en.opensuse.org/openSUSE:Packaging_for_transactional-updates
+
+v2:
+- Fix accidental deletion of btrfs subvolume (boo#1130669).
+- Fix detection of btrfs boot subvolume if its /etc/fstab entry contains
+ leading slash for subvol= mount option.
