I have tested grub2-2.02-0.23.fc23.x86_64 installed on an Fedora 21
I succeeded in booting a CentOS 7 with XFS from the fedora boot menu, but I still cannot boot a SLED 12 with XFS from the fedora boot menu.
Using my openSUSE 13.2 I can boot CentOS 7 and SLED 12.
If you need more information, please advise me, how to create a log from grub2.
